There is growing interest in the use of short-season summer annual legumes or grasses as cover crops and green manures in vegetable production systems. Cover crops can provide a significant source of nitrogen (N) for subsequent crops; reduce erosion, runoff, and potential pollution of surface waters; capture soil N that might otherwise be lost to leaching; add organic matter to the soil; improve soil physical properties; impact insect and disease life cycles; and suppress nematode populations and weed growth. There can be potential drawbacks, such as cooler soils in the spring, and the additional cost of seeding the cover crop. These factors must be considered depending on the particular cash crops and cover crops being grown.
This publication discusses growing and harvesting head lettuce, the most important salad vegetable grown in the United States. Per-capita consumption exceeds 25 pounds annually. In North Carolina, the crop can be grown as both a spring and fall crop in eastern North Carolina and even during midsummer in western North Carolina at elevations higher than 3,000 feet.
Sooner or later most home gardeners think about growing roses. Landscape uses are quite varied because of the many different types of roses. They can be mass planted in beds, used as specimen or trained plants, planted as screens or hedges, or located near fences or arbors and allowed to climb. Several miniature cultivars can even be used as a ground cover or as edging material. Roses are available in almost any color imaginable and are suited to a number of sites.
English ivy (Hedera helix) is a shade-tolerant, woody perennial vine. When established it creates a dense ground cover with attractive dark green foliage. But, left un-checked this introduced plant invades woodlands, climbs (and kills) trees and is considered an invasive species. Pursuing the internet you can find several “recommendations” for controlling English Ivy. Some good, some are questionable. This publication describes cultural and chemical control options.
Annual flowers offer the gardener a chance to experiment with color, height, texture, and form. Besides providing a massive display of color, annuals are useful for filling spaces where perennial flowers have died, to cover areas where spring-flowering bulbs have died back, and to fill planters, window boxes, and hanging baskets. Annual flowers bloom more quickly and for a longer period than any other group of plants. They are easy to grow, sturdy, and relatively inexpensive.

Japanese stiltgrass (Microstegium vimineum) Identification and Management: Brief Description: Japanese stiltgrass (also known as annual jewgrass, bamboograss flexible sesagrass, Japanese grass, Mary’s grass, microstegium, Nepal microstegium, or Vietnamese grass) is a summer annual commonly found in shady, moist areas, and is spreading rapidly in woodlands as well as shaded landscapes and low maintenance turf throughout the southeastern U.S., Mid-Atlantic States and north to New England. Japanese stiltgrass germinates in early spring, several weeks before crabgrass, yet flowers and seeds much later, from mid-September through October. It has broader, shorter leaves than most other annual grasses; somewhat resembling broadleaf signalgrass or spreading dayflower. After frost, the foliage and wiry stems turn a distinctive light tan in color and persist through the winter. Vegetative identification characteristics include: rolled vernation, a very short membranous ligule, and leaf blades that are shorter and broader than most other grasses.
This factsheet, part of the publication Insect and Related Pests of Vegetables publication, includes an identification key and descriptions of pests in asparagus production.
Muscadine grapes are well adapted to the Coastal Plain of North Carolina, where temperatures seldom fall below 10°F. Considerable injury generally occurs where winter temperatures drop below 0°F. Muscadines have a high degree of tolerance to pests and diseases that makes the production of bunch grapes nearly impossible in eastern North Carolina. There is no other fruit with such strong personal associations for so many native North Carolinians.
Much success in growing tomatoes can be attributed to use of a few proven techniques. Choosing a variety that has proven to be a true performer should be at the top of every gardener's list. Better Boy, Whopper, Celebrity, and Mountain Pride are among some of the best selections. Better Boy, Celebrity, and Whopper are VFN, which means they carry resistance to verticillium wilt, fusarium wilt, and root-knot nematodes. It is best to experiment with several varieties in order to find the ideal tomato for your taste buds.
This publication discusses growing and harvesting bloodroot, a spring wildflower used to produce natural red, orange, and pink dyes, in North Carolina.

Pumpkins were used by early settlers much as we use them today – for food and decoration. This factsheet covers growing and harvesting pumpkins in North Carolina.
Turfgrass, trees, and shrubs are desired in most landscapes because they are attractive and useful. Unfortunately, growing turfgrasses in the presence of trees and shrubs can be a formidable task because each plant group competes with the other for the light, water, and nutrients that are essential for survival and growth. The desired effects of trees sometimes make it difficult to grow turf. When trees and shrubs are used to provide screening and privacy, the reduced wind movement and sunlight often increase the chance for disease. Even so, homeowners can take steps to improve the performance of a lawn growing in shade.
Many vegetables are well adapted to planting in the summer for fall harvest. Planting a fall garden will extend the gardening season so you can continue to harvest fresh produce after earlier crops have finished. The fall harvest can be extended even further by providing protection from early frosts or by planting in cold frames or hotbeds.
This factsheet summarizes the characteristics of the millipedes and addresses how to control them as an insect in turf.
Manual removal of weeds is time consuming, expensive, and often results in damage to landscape plants when intertwined roots of both the weed and the ornamental plant are pulled up.

Commercial blueberries are generally planted in low areas with high organic-matter content. These sites satisfy the cultural requirements of blueberries for a constant and uniform moisture supply. However, on cold, still nights when radiation frosts occur, heavy cold air from higher surrounding areas "drains" into the low areas causing lower temperatures. Also, the high organic content, especially if the soil is dry, acts as an insulator to restrict heat in the soil from moving up around the plants. The cultural requirement for a uniform soil moisture makes selecting higher sites that are less subject to radiation frosts much less practical than with other fruit crops. This factsheet discusses protecting blueberry plants from freezing.
Fresh market (slicer) cucumbers have been produced commercially in North Carolina for many years. The average yield from commercial fields has been 850 to 950 bushels per acre or 2 to 3 times the average yield from non-trellised fields. This publication covers growing and harvesting fresh market cucumbers.

An herb is any plant used whole or in part as an ingredient for health, flavor, or fragrance. Herbs can be used to make teas; perk up cooked foods such as meats, vegetables, sauces, and soups; or to add flavor to vinegars, butters, dips, or mustards. Many herbs are grown for their fragrance and are used in potpourris, sachets, and nosegays; or to scent bath water, candles, oils, or perfumes. More than 25% of our modern drugs contain plant extracts as active ingredients, and researchers continue to isolate valuable new medicines from plants and confirm the benefits of those used in traditional folk medicine.

Water is an essential component for plant growth. In turfgrasses it comprises 75 to 90 percent of the fresh weight of the plant, and irrigation is a key cultural practice in turfgrass management. Only 1 percent of the water absorbed is utilized for metabolic activity. By considering the factors that contribute to water loss, turfgrass managers can devise effective irrigation plans for specific sites.
A properly planted tree or shrub will be more tolerant of adverse conditions and require much less management than one planted incorrectly. Planting technique impacts water quality as it minimizes water, fertilizer and pesticide use. When making decisions on planting techniques, one should consider how the plant was grown in the nursery, the plant's drainage requirements, the soil type and drainage characteristics, and the availability of irrigation water. The plant should be specifically appropriate to the site, or the site should be amended to specifically fit the plant.
Establishing and maintaining quality annual color beds requires a plan to prevent and control weeds.

Herbs should be harvested when the oils responsible for flavor and aroma are at their peak. Proper timing depends on the plant part you are harvesting and the intended use. Herbs grown for their foliage should be harvested before they flower. While chives are quite attractive in bloom, flowering can cause the foliage to develop an off-flavor. Harvest herbs grown for seeds as the seed pods change in color from green to brown to gray but before they shatter (open). Collect herb flowers, such as borage and chamomile, just before full flower. Harvest herb roots, such as bloodroot, chicory, ginseng, and goldenseal, in the fall after the foliage fades.
Many farmers and home gardeners have reported damage to vegetable and flower crops after applying horse or livestock manure, compost, hay, or grass clippings to the soil. The symptoms reported include poor seed germination; death of young plants; twisted, cupped, and elongated leaves; misshapen fruit; and reduced yields. These symptoms can be caused by other factors, including diseases, insects, and herbicide drift. Another possibility for the source of these crop injuries should also be considered: the presence of certain herbicides in the manure, compost, hay, or grass clippings applied to the soil.
Several decades ago, when orange-fleshed sweet potatoes were introduced in the southern United States, producers and shippers desired to distinguish them from the more traditional, white-fleshed types. The African word nyami, referring to the starchy, edible root of the Dioscorea genus of plants, was adopted in its English form, yam. Yams in the United States are actually sweetpotatoes with relatively moist texture and orange flesh. The following information outlines several differences between sweetpotatoes and yams.
To insure a successful azalea planting, cultural requirements, planting techniques, and maintenance should be understood.

Basil is a popular herb known for its flavorful foliage. The fresh or dried leaves add a distinctive flavor to many foods, such as Italian style tomato sauces, pesto sauce and salad dressing. The essential oils and oleo-resins may be extracted from leaves and flowers and used for flavoring in liqueurs and for fragrance in perfumes and soaps. This factsheet discusses growing and harvesting basil in North Carolina.
In most of the south, sweet corn can be produced from early spring until fall. However, sweet corn does have some specific environmental and cultural needs that must be met for the plant to produce high-marketable yields. Corn is a warm-season crop that requires high temperatures for optimum germination and rapid growth. In general, sweet corn does not tolerate cold weather, and frost will injure sweet corn at any stage of growth. Other stressful climatic conditions, such as drought or flooding, can reduce yields and cause small, deformed ears.

Turnips and rutabagas are among the most commonly grown and widely adapted root crops. They are members of the Cruciferae or mustard family and belong to the genus Brassica. The two are similar in plant size and general characteristics. Turnip leaves are usually light green, thin and hairy, while the rutabagas are bluish-green, thick and smooth. The roots of turnips generally have little or no neck and a distinct taproot, while rutabaga roots are often more elongated and have a thick, leafy neck and roots originating from the underside of the edible root as well as from the taproot.
This publication discusses the Brussels sprout, a cool season crop, belonging to the cabbage family, and closely related to cauliflower, broccoli, kale, collards, etc. Like cauliflower, it thrives best in a cool humid climate, thus commercial production of this crop is concentrated in the "fog-belt" of California with limited production in the Long Island, New York area. The edible portion of this crop is the "bud" or small cabbage-like head which grows in the axils of each leaf. Occasionally the tops are used as greens.
This factsheet discusses the biology and control of ocellate gall midges, which cause red and yellow spots on the surface of red maple leaves.
The term perennial is frequently used by gardeners to refer to herbaceous perennial flowers. Most herbaceous perennials grow and flower for several years. Some perennials are short-lived – surviving for only three or four years. In the fall, the tops of herbaceous perennials (leaves, stems, and flowers) die down to the ground while the root system persists through the winter. In the spring, the plant grows new leaves from its crown or roots. Plants that grow from bulbs and bulb-like structures are also herbaceous perennials but are often classified separately as flowering bulbs.
There are a number of reasons to prune woody plants. One of the most important is to maintain a healthy, safe plant. This is particularly true of trees since dead limbs, topped branches and poor form can lead to unsafe conditions. You can reduce the amount of pruning needed by selecting the right tree for the site. Trees can range in size from 20 to more than 100 feet, and many can get large very quickly.
This factsheet summarizes the characteristics of wild violet.
Among the early spring-flowering trees, the dogwood is regarded by most North Carolinians as unrivaled in attractiveness either in its natural woodland habitat or in cultivated landscape gardens. This small, ornamental tree offers landscape interest for all seasons, beginning with its floral display in spring and followed by pleasant green foliage (casting a light shade) in summer. Fall in North Carolina is enhanced by the brilliant show of red, orange, and scarlet foliage along with the bright-red fruit borne in small clusters. In winter, button-shaped buds are prominent on the tips of the twigs. The interesting bark texture and branches help create an excellent winter silhouette.

Homeowners and professional landscapers depend on mulch in the ornamental plantings for several reasons. Functionally, mulches discourage weeds from growing, conserve moisture during drought periods, allow better use of water by controlling runoff and increasing water-holding capacity of light, sandy soils. Mulches help maintain a uniform soil temperature. A 3- to 4-inch layer of mulch can add to the aesthetic value of a garden while protecting the base of plants from being injured by mechanical equipment.
Southern peas originated in India in prehistoric times and moved to Africa, then to America.

Growing your own transplants from seeds indoors can give you a head start on the growing season. In some cases, it may be the only way to obtain plants of a new or special cultivar (variety) that is not widely available through garden centers. To obtain vigorous plants, start with high-quality seed from a reliable source. Select cultivars which provide the plant size, color (flower, foliage, or fruit), and growth habit you want. Choose cultivars adapted to your area. Many vegetable and flower cultivars are hybrids. They may cost more than open pollinated types, but they usually have more vigor, more uniformity, and better growth than non-hybrids.

Strawberries are a welcome addition to any home garden. They are relatively easy to grow, require a minimum of space, and virtually no chemicals are needed. From as few as 25 transplants to start a matted row, a berry yield in excess of 50 pounds can be achieved one year after planting. Strawberries require a site that is open to direct sunlight most of the day. Try to avoid very low-lying areas prone to spring frosts, and you should definitely plan to purchase a white spunbonded row cover to protect open strawberry blossoms from spring frosts/freezes. The same cover may be used for bird control during harvest.

There are several vines which should interest North Carolina gardeners and landscapers. Vines, when used correctly, can be quite an aesthetic and functional addition to the landscape. Basically, there are three types of vines: those that climb by attaching tendrils to a means of support, those that climb by attaching rootlike arms to a wall, and those that climb by twining. The type of vine which is planted will determine the necessity for a supporting fence, arbor, or wall.
This factsheet covers celery, which could be a very profitable crop in North Carolina. A harvest period in late June or early July, and one in October, would fill market voids when other major celery producing areas are not harvesting. Celery, however, is not an easy crop to grow. Although it is a cool season crop, exposure of juvenile plants to temperatures below 40 to 50ºF for more than 5 to 10 days can cause premature bolting, making the crop unsalable. Special attention must be given to maintaining a steady water supply and providing the proper amount of nutrients to allow for constant growth.
Weeds are unwanted plants in gardens that reduce available moisture, nutrients, sunlight and growing space needed by crop plants. Their presence can reduced crop growth, quality and yield. In addition, they can make harvest difficult. Weeds also provide cover for diseases, insects and animals (rodents, box turtles, snakes, etc.). Garden weeds are hard to control because they grow rapidly, produce vast numbers of seeds, and spread aggressively by vegetative structures and/or seeds. There are several methods that should be used in a combined, coordinated effort to control weeds. They include cultural, mechanical and chemical methods.

Cauliflower is a cool season crop, closely related to broccoli, cabbage, kale, turnips, and mustard. It is more exacting in its climatic requirements than most other crops in this family. It grows best in a comparatively cool temperature with a moist atmosphere. With proper management cauliflower can be grown in North Carolina as either a spring or fall crop, although the fall crop will generally produce better quality.
Annual and perennial grasses can be selectively controlled in most broadleaf crops and landscapes using postemergence herbicides that control only grasses -- chemicals often referred to as “postemergence graminicides”. There are four graminicides labeled for use in horticultural crops – fenoxaprop, fluazifop-p, sethoxydim and clethodim. Each graminicide is systemic (translocated) and has short-term soil residual (about 2 weeks). Although each herbicide kills grasses in the same way (acting upon the same site of action), they differ in their effectiveness on grass weeds, safety on crops, and labeled uses.
This factsheet summarizes the characteristics of nematodes and addresses how to control them in turf.
One of the most important considerations in developing a landscape plan is maintenance. Currently, many homeowners desire a low-maintenance landscape. A popular project for home gardeners is the reduction of lawn areas and problem spots by the incorporation of the "natural area." This is most easily accomplished with a 3- to 4-inch layer of organic mulch such as pine needles, compost or pine straw. Although the area is to appear natural, it should not detract from the overall landscape appearance.
This Entomology Insect Note describes the biology and control of aphid pests of ornamental trees, shrubs, and flowers.
Each of us are subjected to stresses and pressures every day in our home, work, and living environment; plants are no different. Unfortunately, there is no "stressless" environment, and there is no totally stress-resistant bedding plant. Each site has its stress level and each plant has its tolerance level. There are steps that can be taken to reduce or avoid stress in the landscape. However, no program can prevent all problems, and the key to successful landscape color using bedding plants is to match the particular site with specific plant species.
Sprouts from mung bean (Phaseolus aureus) have been used for food since ancient times. These sprouts have a nutrient value similar to asparagus and mushrooms, which contain high quantities of Vitamin A. Sprouts can be canned or frozen in addition to eating them fresh. Mung bean seeds can be purchased from mail-order commercial seed companies and health food chain stores. (Caution: Regardless of the source, do not use seeds that have been treated with a fungicide. Treated seeds are not edible and can be recognized by the coating of pink or green dust on the seed coat.)
Leafy greens, such as turnips, mustard, collards, kale, and spinach are cool season crops. They should be grown during early spring or fall for maximum yields and quality, but this season can be extended if markets warrant. Kale and spinach can withstand temperature into the upper teens and are often harvested through winter in the east. The other greens may withstand medium frosts.

The Amaryllis (Hippeastrum) is a true bulb that originated in the tropical areas of South America. Thus, it is a tender bulb. It performs best when grown under warm (70 to 75°F) temperatures for 9 to 10 months to promote flowering and vegetative growth, followed by 2 to 3 months of either cool (55°F) dry storage or cool (55°F) growing conditions. The use of one of the latter conditions is required to promote reflowering of the bulb.
Seed dormancy is nature's way of setting a time clock that allows seeds to initiate germination when conditions are normally favorable for germination and survival of the seedlings. For example, dogwoods produce mature seeds in the fall, but conditions are not suitable for seedling survival at that time. Thus, dogwoods have developed a mechanism that keeps the seeds dormant until spring when conditions are favorable for germination, as well as, seedling growth and survival.
Shrubs in this category are useful in landscape situations as hedges, small screens, accent plants, large mass plantings, and large foundation shrubs. These plants can be pruned periodically and maintained at a reasonable size.

Phytophthora leaf blight and root rot is a devastating disease which causes a leaf blight and root rot on ginseng. The disease is caused by a fungus, Phytophthora cactorum, which produces spores that are spread by wind, rain, splashing water, and surface water runoff. Root rot is the most serious form of the disease. Therefore, if foliar symptoms are present, preventing spread of the disease from foliage to roots is essential.
Grapes are welcome summer treats that can be eaten fresh, processed into jellies, jams, juice or even fermented into wine. Grapes are adapted to many soil types, and can be quite long-lived. There are basically two kinds of grapes grown in North Carolina, bunch grapes and muscadine. Bunch grapes produce berries in large clusters, and grow best in the mountains and piedmont areas. In coastal plain areas, Pierce's disease kills or shortens the life expectancy of many popular bunch grapes. Muscadine grapes, exemplified by the Scuppernong variety and noted for having smaller clusters, are not affected by this disease.

Frost forms on solid objects when the water vapor in the atmosphere changes from its vapor phase to small ice crystals. Frost is not frozen dew. If you see frost than you know that the temperature of the object it is on reached 32°F or lower. However, the air temperature, measured at five feet above ground in the vicinity of this object, is likely several degrees higher. Conversely, not every air temperature recorded at or below 32°F means frost formed on solid objects in the area. In spite of this, the average date of the last spring air temperature of 32°F has traditionally been called the last frost date. The dates presented in this leaflet are the average date of the last recorded air temperature at 32°F or lower for the period 1951 - 1980.

A careful selection of plants is very important for coastal landscapes as plants must be tolerant of extreme adverse conditions in the natural environment. The most influencing force is salt spray. Sand, temperature and wind are also influencing factors in plant choice.
Precision seeding is defined as the placing of desired numbers of seeds at a precise depth and spacing. Precision seeding has many advantages for the vegetable grower over conventional dribble (Planet Jr.) or multiseed drop-plate seeding systems (most corn planters). However, the seeding accuracy is not a substitute for proper land preparation, irrigation, and other crop management practices necessary to obtain a good stand of a vegetable crop. Precision seeding simply allows the vegetable grower to reduce cost and increase reliability of his crop production.

Conversely, not every air temperature recorded at or below 32°F means frost formed on solid objects in the area. In spite of this, the average date of the last spring air temperature of 32°F has traditionally been called the last frost date.
Broccoli-raab (also known as rapa, rapine, rappone, fall and spring raab or turnip broccoli) is a rapidly growing annual when grown in spring, but a biennial in fall plantings. The leaves with the seed-stalks, before blooming, are cut for greens and are sold to ethnic markets (primarily Italian).
Cool-season leafy greens face a different weed spectrum than warm-season crops. The presence of weeds in harvested greens can result in lower prices or rejection at market. Learn about the cultivation and herbicide options that growers can use to avoid weed competition and contamination.
Healthy plants are important components of urban landscapes. These plants, however, are subjected to attacks by a myriad of pests while they are being grown in a nursery or maintained in a landscape. The ultimate goal of a successful ornamental plant pest management program is to improve the quality of plants (nurseries and greenhouses) and plant care services (landscape care operations) while minimizing pesticide use and the negative impacts of pesticide use to the environment, workers, clients, and other non-target organisms. To do so, ornamental plant growers and landscape care professionals have to understand the basic operating principles of integrated pest management, or IPM. The results of IPM can be spectacularly effective when well designed and executed.
Interest in growing herbs for the retail and wholesale market has increased greatly over the past few years. Growers who have had success in the production of bedding plants have found another profitable avenue in herb production. Herbs have cultural requirements similar to bedding plants and it should be easy for greenhouse growers to add herbs to their production schedule. The majority of herbs discussed in this article can be sown, transplanted, and finished by the grower. This publication will focus on the production of the “top twelve” herbs and provides general guidelines for seed propagation.

A growing mix well suited for growing transplants can be prepared by using one part loamy garden soil, one part shredded peat moss, and one part sand. Sterilize this soil-peat-sand mix by baking it in an oven for about one hour at 210°F.
In the case of specialty or non-traditional small fruit crops in the Southeast, red raspberries seem to get the most interest and coverage by newspapers and popular press. In North Carolina, red raspberries developed in northern United States and southern Canada have difficulty in our hot, humid summer climate of the piedmont and coastal plain. And, in the foothills and mountains of western North Carolina, the raspberry 'floricanes' are especially prone to winter freeze injury as temperatures in these areas may fluctuate in January and February by as much as 40-50°F in a given 24 hour period.
Most commercial onions produced in North Carolina are seeded in the fall and harvested in mid- to late-June.

As one travels across North Carolina it is quite evident that azaleas are favorite ornamental plants for home gardeners and professional landscapers. Azaleas offer a wide range of size, form and color, and can be used as specimen plant accents or as a mass planting. Flowering dates are from late March to late June with both ever-green and deciduous types available. Azaleas can be grown all across the state (Zones 6, 7, 8, 9), but in order for these shrubs to grow, mature, flower profusely, and generally contribute to the total landscape, an understanding of the different kinds of azaleas, the culture, and environmental factors is necessary.
Summer and fall flowering bulbs provide another dimension to gardening. They add beauty and interest to the landscape and, since most of them are tender, they offer a unique challenge to the gardener. There are a large number of different types of bulbs, offering variations in forms, fragrances, colors, and lasting brilliance which many summer annuals cannot achieve.
The florists' hydrangea has been an important greenhouse crop for many years. Its popularity and production have both been increasing in the past few years. This leaflet outlines procedures for the greenhouse forcing of dormant, pre-cooled hydrangeas.
The nutritional content, freshness, and flavor that vegetables possess depend upon the stage of maturity and the time of day at which they are harvested. Overly mature vegetables will be stringy and coarse. When possible, harvest vegetables during the cool part of the morning, and process or store them as soon as possible. If for some reason processing must be delayed, cool the vegetables in ice water or crushed ice, and store them in the refrigerator to preserve flavor and quality. The following guidelines can be used for harvesting vegetable crops.

The per-capita consumption of processed tomatoes has increased steadily in recent years. This has been due to changes in eating habits and development of new and better products. Over 8 million tons of processed tomatoes are produced in the United States annually. Average yields for the United States are 25 tons per acre while the range is 9 to 40 tons per acre. North Carolina growers can produce high yields of processing tomatoes. Satisfactory color, pH, sugar and acid content needed to produce a fine quality canned product can be attained if tomatoes are grown according to recommended practices.
Wet, poorly drained soils present one the most difficult challenges for growing plants in the landscape. Excessive moisture displaces oxygen in the soil and plant roots can suffocate as a result. Many plants are intolerant of having their roots submerged for extended periods of time. Even though standing water may not be present, poor drainage is often responsible for reduced growth and survival of plants in our landscapes.
This table presents information on postemergence herbicides registered for use on woody ornamentals.
Weeds reduce the aesthetic qualities of landscape plantings and compete with nursery crops for nutrients, water, and light. Root systems compete for nitrogen and water. Even seemingly non-competitive weeds like bittercress (Cardamine spp.) have been shown to reduce growth of container-grown plants. Tall weeds and vines shade crops, reducing photosynthesis and growth. Vining weeds such as morningglory (Ipomoea spp.) are particularly damaging because they disfigure stems and new growth. In landscape plantings, weeds must be controlled or removed to maintain quality aesthetics. Weeds may also need to be removed for health and safety reasons
Lawns are ecosystems that impact surface and groundwater systems. The grasses found in lawns clean the environment by absorbing gaseous pollutants and intercepting pesticides, fertilizers, dust, and sediment. Irrigation water properly applied to lawns remains on site to recharge water supplies. In addition, grasses release oxygen and reduce glare, noise, and summer temperatures. Proper management practices need to be developed and followed to protect this environment. The purpose of this publication is to provide you with management strategies to preserve and protect water resources.

We depend on plants to solve our functional and aesthetic needs in various landscape situations. A popular group of plants being recommended and used in modern landscapes is intermediate and small-sized trees. The trees in this category mature to a particular size and are quite "well-behaved" in the landscape. Generally, the trees, both evergreen and deciduous, mature to a height of 35 feet or less.
Deer are among the most beautiful and graceful but troublesome wildlife in North Carolina. Over the past 10 to 15 years, damage to ornamental plants in landscapes and nurseries, by white-tailed deer has increased dramatically in all 100 counties. This situation has become a problem due to the increase in the size of the deer population in North Carolina and to the urbanization of rural areas. Conflicts between deer and landscaped spaces are expected to increase, as more rural areas will be developed.
Annual sunflower is a native of North America with an original range from the Great Plains to the West Coast. Pot sunflowers have been popular in Europe for a number of years. Pot sunflowers are a quick crop to produce and offer an opportunity for growers to capitalize on the current consumer demand for the plant.
The use of wildflowers in the landscape has increased since Lady Bird Johnson first promoted them in the late 1960s and early 1970s. Wildflowers were further popularized by the "Meadow in a Can" seed collections that were marketed in the early 1980s. A number of books have been written that describe methods for planning and planting wildflowers, however, few recommendations are available regarding maintenance and long-term weed management. In wildflower plantings, weed management is a complex system that requires knowledge of the specific wildflowers and weeds, environmental conditions, and control methods. Therefore, the objective of this leaflet is to discuss weed management strategies that can be applied to the planning, establishment, maintenance and renovation stages of a naturalized wildflower planting.
Lack of yard space is no excuse for not growing a vegetable garden. Regardless of whether you live in an apartment, condominium or mobile home, some space us available for growing a few of your favorite vegetables. However, the area you choose to grow your garden must receive five hours or more of sunlight daily. As a general rule, leafy vegetables such as cabbage and mustard greens can tolerate more shade than root vegetables like radishes and beets. Vegetables that bear fruit such as peppers, tomatoes, and cucumbers will need the most sun.
Vegetables are 80 to 95 percent water. Because they contain so much water, their yield and quality suffer very quickly from drought. When vegetables are sold, a "sack of water" with a small amount of flavoring and some vitamins is being sold. Thus, for good yields and high quality, irrigation is essential to the production of most vegetables. If water shortages occur early in the crop's development, maturity may be delayed and yields are often reduced. If a moisture shortage occurs later in the growing season, quality is often reduced even though total yields are not affected.
This first of four publications in the Pruning Trees & Shrubs series introduces basic pruning concepts and key terms. Subsequent publications in the series provide more information on woody plant biology, necessary tools and pruning guidelines for general purposes and specific species.

This publication discusses ways that gardeners can protect water quality and avoid runoff and soil erosion.
Most garden asters are cultivated varieties of the fall-blooming wildflower, Aster novi-belgii, or Michaelmas daisy. They are native to the United States and can be seen blooming along roadsides during the fall. From the wild types, Danish breeders have selected for new colors and compact shape. As a floriculture crop, they can be grown for cut flowers, an indoor pot crop in four-inch or 6-inch pots, or an outdoor perennial in 6-inch pots or larger. This leaflet covers the commercial production requirements for perennial garden asters.
New Guinea impatiens have steadily increased in popularity since their introduction into the United States in 1972. Today's varieties offer a wide range of flower colors as well as variegated foliage types. The versatility of this plant allows for its sale as bedding plants, 4 inch potted plants, and up to 12 inch hanging baskets. This factsheet offers advice on growing impatiens.

Poinsettias are the traditional Christmas plant because of their colorful bracts. The bracts are actually modified leaves and the yellow cyathia in the center of the bracts are the true flowers. Plant breeders have introduced many new cultivars over the past few years and there are more than 100 cultivars currently available. The array of colors range from red, pink, white, salmon, to bicolors. With these new, longer lasting cultivars being available, it is possible for a properly cared for poinsettia to remain beautiful in the home for 2 to 3 months.
Selecting trees for use under utility lines presents a unique challenge. It is often desirable to have trees that are large enough to provide shade, architectural effects, and ornamental features, all without interfering with overhead utility lines. In this publication, we have listed trees that have a typical mature height of less than 30 feet.
Asparagus has been considered a garden delicacy since Roman times. Any home gardener can grow and enjoy this spring vegetable. Asparagus is a perennial. If you plant and manage properly it will produce for 15 years or more. Since this crop will occupy the land for many years you should start the asparagus bed properly -- location, soil type, soil fertility, size and age of crowns and correct planting are important.

This leaflet is designed to introduce commercial growers to the alternatives available for height control and suggest appropriate methods for different situations.
The use of weather information in crop management and particularly the aspects of disease and insect management is growing at a fast pace. Two things drive this growth. Research has provided the understanding of the weather disease and weather insect interactions and technological advances in meteorology and communications have allowed easier and faster access to weather observations. Also, the relatively low cost of the computer systems that provide the decision support for applying this knowledge to every day operations have made them more affordable and practical.
This publication offers a selected list of labs specializing in testing and analyzing samples of greenhouse root substrate, irrigation water, fertilizer solution and plant tissue. Providing the proper nutrition program for your plants is important for controlling growth.
Many people who live in an apartment, condominium, or mobile homes do not grow a vegetable garden because space is not available for a garden plot. Lack of yard space is no excuse for not gardening, since many kinds of vegetables can be readily grown in containers. In addition to providing five hours or more of full sun, attention must be given to choosing the proper container, using a good soil mix, planting and spacing requirements, fertilizing, watering, and variety selection.
This publication covers the identification and control of Florida betony, an aggressive, rhizomatous perennial in the mint family categorized as a category B noxious weed in North Carolina.
Growing strawberries as an annual crop on black plastic requires a different weed management strategy than the perennial matted row strawberries. When black plastic is combined with fumigation by methyl bromide, excellent control of most weeds in the row can be expected. However, weeds that have hard seed coats, such as vetch and clover, emerge for long periods of time and can establish in the row. They emerge in late fall or spring, grow under the plastic for a period of time, and emerge from any holes in the plastic.

Integrated Pest Management (IPM) can be defined as a sustainable approach to managing pests by combining cultural, biological, and chemical tools in a way that minimizes economic, aesthetic, health, and environmental risks. A first step in implementing an effective IPM program is to maintain healthy, vigorous plants, which are much less likely to have pest problems. Therefore, an integrated pest management program will also consider cultural practices that lead to healthy and resilient plantings.
This publication, part of the 2017 Southeastern US Pest Control Guide for Nursery Crops and Landscape Plantings, discusses control measures for deer, rabbits, voles, and beavers in the landscape.
Ornamental cabbage and kale have been the traditional ornamental vegetables for providing colorful and attractive foliage during the fall and winter months. Recently leafy vegetables, in particular oriental mustards, have become popular for landscape plantings during the cool season. Leafy vegetables which have been popular in salads and stir-fry dishes are now being adopted by curators of botanical gardens and landscape contractors as specimen plants, border plants, and in mass plantings. Planted with pansies and garden mums, these vegetables offer a change of texture and foliar color.
Water quality and quantity issues are extremely important in container production of plants. This article addresses both quality and quantity issues for greenhouse and nursery production from a best management practices view.
Mulching trees and shrubs is a good method to reduce landscape maintenance and keep plants healthy. Mulch helps conserve moisture - 10 to 25 percent reduction in soil moisture loss from evaporation. Mulches help keep the soil well aerated by reducing soil compaction that results when raindrops hit the soil. They also reduce water runoff and soil erosion. Mulches prevent soil and possible fungi from splashing on the foliage - thus reducing the likelihood of soil-borne diseases. They help maintain a more uniform soil temperature (warmer in the winter and cooler in the summer) and promote the growth of soil microorganisms and earth worms.
Impervious surface cover increases tree stress and reduces tree condition. We developed an impervious surface threshold to help tree care professionals select planting sites where red maples will thrive. In this publication we describe how to estimate impervious surface cover, on site, with the Pace to Plant technique.

More than 40 sedge species may be found in North Carolina landscapes. Although grass-like in many ways, and the nutsedges are often referred to as “nutgrass”, they are not grasses and require different control measures than grasses. Sedges are easily distinguished from grasses by their leafy shoots that produce leaves in “3s” resulting in stems that are triangular in cross section. In contrast, shoots of grasses are flat or round in cross section.
"Paperwhite" Narcissus is one of the easiest flower bulbs for homeowners to force. Commercially, several types are available. Some cultivars (varieties) have pure white flowers while others have white perianths with light yellow cups. Paperwhites originate in the Mediterranean and are tender bulbs. Thus, they can be grown outside only in Climatic zones 8 to 11. Unless one lives in one of these zones, forced bulbs should be discarded.
Two hydrangea species are native to the southeastern United States -- Hydrangea arborescens and Hydrangea quercifolia. Both are bold-textured, deciduous shrubs which produce small, fertile flowers. Many selections are considered more garden-worthy than the native species because they display large, sterile florets.

Solar radiation provides the energy to warm our atmosphere and allow plant growth and animal life to exist on earth. The amount of “possible solar radiation” does not depend on the weather and is constant for a given date from year to year. The variation in “possible solar radiation” by date throughout the year is due to the earth’s axis of rotation, which affects the hours of daylight and the angle (directness) of the sun’s rays. The amount actually received, however, does vary, mainly due to the variation in amount of cloudiness.
Causing spring-flowering bulbs such as daffodils (Narcissus) to flower by other than naturally occurring conditions is called "forcing." This practice is carried out by commercial growers the world over. With a little care and effort, homeowners can have a steady supply of daffodils (Narcissus) from late December through April. Forcing bulbs should be a challenge to those who are interested in plants.
When it comes to weeds, “start clean – stay clean” should be the moto of every nursery manager. This is especially true for producers of herbaceous perennials. Although we can control most grassy weeds with postemergence herbicide; otherwise, we have few herbicides to use when weeds get out of hand. Furthermore, the herbicides labeled for use in herbaceous ornamentals are either safe on many ornamentals and do not control many weeds, or control lots of weeds but are safe on only a few ornamentals. Consequently, to manage weeds effectively a comprehensive nursery weed management program including exclusion, sanitation, preemergence herbicides, some postemergence herbicides and hand weeding will be needed.
This chart presents the grams of herbicide needed for circular landscape beds of various diameters.
This publication presents tables of average monthly precipitation values for several North Carolina cities and towns.
This table presents information on preemergence herbicides registered for use on woody ornamentals.
Ornamental cabbage and kale have become increasingly popular as fall crops because they have colorful, long lasting foliage. They will often remain colorful until temperatures drop and are well suited to areas of the Southern United States which have mild winters. Ornamental cabbage and kale are also excellent complements to garden chrysanthemums and fall pansies, and will help increase overall sales.
With the increasing diversity of North Carolina agriculture, it is important to document and assess the presence of the commodities produced in the state. Crop data are publicly maintained on only the top 20 or so specialty crops, yet state and federal decisions impact hundreds of individual crop species. Because little information is available for most specialty crops, it must be gleaned from many different sources.

Causing spring-flowering bulbs like hyacinths to flower by other than naturally occurring conditions is called forcing. This practice is carried out world-wide by commercial flower growers. With planning and effort, any homeowner can have a steady supply of bulb flowers from late December through April. Forcing bulbs is a rewarding challenge to those interested in the growth and development of plants.

Each year, a portion of the state's fruit and vegetable crop is lost to low temperature damage. Protection methods exist. This leaflet seeks to explain the occurrence of frosts and freezes and to provide information on protection methods.
This comprehensive guide will help master gardeners diagnose many insect and mite problems and to decide whether to bring a particular problem to the attention of a county agent.
The decisions of when to turn an irrigation system on and off for frost protection are complex and difficult. This guide presents a procedure to follow in making these decisions. This guide is based on the assumption that you have completed certain tasks prior to the night of the decision making. These tasks encompass important planning decisions that are made well ahead of the frost season.

Phoma macrostoma, a potential biocontrol agent for turfgrass weeds, was isolated from Cirsium arvense plants in Canada and is being tested in other regions of North America for control of broadleaf weeds in turf. This research was conducted to investigate the effects of varying temperature conditions on Phoma macrostoma control of seedling broadleaf weeds. Experiments were conducted in growth chambers to compare the efficacy of three doses of Phoma macrostoma on two species, Senecio vulgaris and Lamium amplexicaule grown in 4 temperature regimes – 15/20, 20/25, 25/30 and 30/35°C (dark / light period) temperatures. These data suggest that high temperatures common in the southeastern United States should not be an impediment to activity of Phoma macrostoma efficacy, and may actually improve the control of some broadleaf weed species.
