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.

This article describes and defines the different types of insects that sting and are also often mistaken for honey bees.
Honey bees, like all other living things, vary in traits such as temperament, disease resistance and productivity. The environment has a large effect on differences among bee colonies (for example, plants in different areas yield different honey crops), but the genetic makeup of a colony can also impact the characteristics that define a particular group. Beekeepers have long known that different genetic stocks have distinctive characteristics, so they have utilized different strains to suit their particular purpose, whether it be pollination, a honey crop or bee production.

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.

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.

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.

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.

Large trees are dominant features in the landscape. Many plans rely on trees for several design functions: to provide background, enclosure, define spaces, help reduce noise and unsightly views. Trees also provide needed shade, channel breezes, and break forceful winds. They also help the environment by filtering pollutants and exchanging oxygen for carbon dioxide.
There are several selected pines species which are used in North Carolina landscapes, most being large tree forms. Pines are important to North Carolina not only for the ornamental value but also for lumber, watershed management, resin, turpentine and Christmas trees. There are more than 100 species of the genus Pinus recognized worldwide, of which 36 are native to the United States.
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.
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 leaflet was written to give growers production advice for pansies.
When onions are harvested in the green or immature stage they are called "green bunch onions." These onions are sold in bunches tied with a rubber band. This is a popular crop for home and market gardeners in the fall, winter and early spring. Acreages are usually small because of the amount of hand labor required for planting and preparation for market.
This third in a series on pruning offers general tips on pruning most landscape plants.
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.

Immediately after a flood, most farmers, nursery crops producers and grounds maintenance staff have much more urgent matters to worry about than weeds. But, eventually the questions arise: Has my preemergence herbicide washed away? How do I know? Should I re-treat? What’s going to happen now? Unfortunately there is no way to provide definitive answers to these questions. But this publication offers some tips and suggestions that will help you plan a response.
During the winter months it is necessary to offer protection to certain North Carolina landscape plants. Winter protection does not mean to keep plants warm, as this is virtually impossible but to provide protection from damaging wind, heavy snow and ice, the alternate freezing and thawing of the soil beneath the plants and heat from the sun on very cold days.

Providing a proper nutritional program is essential for growing top quality plants. Sampling the root substrate for pH and electrical conductivity (EC) with the PourThru extraction method is a quick and simple check of the nutritional status of a crop. The PourThru extraction method allows rapid on-site determination of pH and EC values. The values provide clues about a crop’s performance before deficiency or toxicity symptoms appear.
Ethylene is an odorless, colorless gas which acts as a plant hormone. Thus it can be a growth regulator or a harmful pollutant of horticultural crops. Major losses caused by the “death hormone” can occur with high value crops such as greenhouse-grown potted plants and cut flowers, and fresh fruit and vegetables. Economic losses to greenhouse growers from ethylene pollution are reported each year and many more probably occur, but are not correctly diagnosed. This leaflet discusses ethylene sources and symptoms of damage, and how to prevent them
Field heat should be removed from fresh fruits, vegetables, and flowers as quickly as possible after harvest. Each commodity should be maintained at its lowest safe temperature.
Geraniums require an adequate supply of the essential nutrients and a slightly acidic pH. This leaflet covers some of the basic considerations for fertilizing zonal, ivy, and regal geraniums.
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.

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.
The symptoms and treatment techniques of southern stem blight in strawberries are discussed in this factsheet.
This chapter discusses the principles of grapevine dormant pruning, reviews reasons for vine training, and describes systems appropriate for use in North Carolina. Profitable grape production requires that grapevines be managed so that a large area of healthy leaves is exposed to sunlight. Such vines are likely to produce large crops of high-quality fruit each year. Grapevines must be trained and pruned annually to achieve this goal. The training system chosen generally dictates how the vines are pruned. Thus, pruning practices and training systems are discussed together in this chapter.

This article contains an overview of weed management practices and recommendations for pansy and viola plantings
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
The kiwifruit is a large, woody, deciduous vine native to the Yangtze Valley of China. In the Eastern United States, kiwifruit vines have fruited at Virginia Beach, Virginia, and at several locations in South Carolina, and are part of evaluation programs in Alabama and Georgia. The first commercial shipments began in 1980 from a planting in South Carolina located about 30 miles north of Augusta, Georgia. This publication discuses the history of kiwifruit planting in North Carolina and considers the potential to grow the fruit in the state's climate.

This publication, chapter 3 of the 2016 Southeast Regional Caneberry Production Guide, discusses the benefits and limitations of selecting various sites to plant blackberries and raspberries.
Drought has always caused nursery crop producers great concern. If irrigation water becomes limiting, growers producing nursery crops in containers may lose their entire crop. Newly planted field-grown crops also sustain heavy losses if they are not irrigated frequently during the first year of production. Although established field-grown nursery stock will survive if not irrigated during periods of drought, they will not grow under these conditions. Adequate moisture during field production will produce field-grown shade trees of marketable size in three to five years. Poorly irrigated plants will take longer to reach marketable size, thus lengthening the time cost of production.

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.
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.
High pH water and high alkalinity in water can be limiting factors in container production of greenhouse and nursery crops. An understanding of both is needed to accurately treat water with a high pH.
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.
Fresh fruits, vegetables, and flowers must be in excellent condition and have excellent quality if maximum shelf life is desired. The best possible quality of any commodity exists at the moment of harvest. From that point on, quality cannot be improved, only maintained. Remember that shelf life begins at harvest.
Every nursery needs to have someone who routinely checks Electrical Conductivity (EC) also called soluble salts, and pH of container crops, potting inventories and irrigation water. Checking EC and pH should be considered part of the quality control and scouting program in the nursery. Results from testing 3 to 5 containers in a irrigation zone each week can be used to schedule irrigation the following week. Comparing leachate solution collected from containers to water collected from irrigation nozzles provides a good insight into nutrient levels in the containers. Checking EC and pH of nursery crops grown in containers doesn't have to be time consuming, complicated or difficult. The intention of this article is to review the procedure and update growers on the Virginia Tech Extraction Method (VTEM), also called the PourThru extraction procedure.
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.
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.

Vineyard establishment involves careful planning, thorough site preparation, vineyard design, planting, and trellis construction. Unlike dormant pruning or other annual activities, designing and establishing a vineyard must be done correctly the first time. In addition, the process must be tailored to the particular site and the grower’s intentions. This chapter discusses the basic steps in establishing a vineyard and offers suggestions for practical methods and materials.There are many alternatives. Although this chapter may be used as the sole source of information for vineyard establishment, it is advisable to obtain and compare information from additional sources before beginning. References provided here include more detailed information on particular aspects of vineyard establishment, such as trellis construction. It is also helpful to visit existing vineyards to examine their design, compare trellising materials, and discuss plant and row spacing.
Grapevines require 16 essential nutrients for normal growth and development (Table 9.1). Carbon, hydrogen, and oxygen are obtained as the roots take in water and as the leaves absorb gases. The remaining nutrients are obtained primarily from the soil. Macronutrients are those used in relatively large quantities by vines; natural macronutrients are often supplemented with applied fertilizers.The micronutrients, although no less essential, are needed in very small quantities. When one or more of these elements is deficient, vines may exhibit foliar deficiency symptoms, reduced growth or crop yield, and greater susceptiblity to winter injury or death. The availability of essential nutrients is therefore critical for optimum vine performance and profitable grape production.
