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.
This calendar provides detailed information for the proper care of centipedegrass.
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.

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.

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.

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.
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 pesticide factsheet covers the use and characteristics of the preemergence herbicide Barricade, Prodiamine or Regalkade G (prodiamine).
Pruning a plant reduces its ultimate adult size and the crop yield in at least the following season. To compensate for this loss of bearing area and yield, other factors, largely economic, must be considered in planning a pruning program.
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.
This publication covers disease control in a variety of crops.
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.

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.

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.

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.

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.

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

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.
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.
Crop prediction or estimation is the process of projecting as accurately as possible the quantity of crop that will be harvested. Why estimate the crop? The most obvious reason is to know how much crop will be present for sale or utilization. Beyond that fundamental reason, it is also important to know whether vines are undercropped or overcropped. In the absence of methodical crop estimations, the experienced grower can rely on past vineyard performance.This approach is subject to error, however, especially in grape regions subject to spring frosts or winter injury, which can greatly affect a vineyard’s productivity from year to year.

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.
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.

Grapes are subject to attack by many different pests, including nematodes, fungal, bacterial, and viral pathogens, insects, and wildlife, such as deer and birds.Weeds, which compete with the vines for soil moisture and nutrients, may also be included in this list. Recognizing and understanding the nature of these pests is essential to minimizing crop losses.This chapter briefly describes the major pests that routinely threaten bunch grapes in North Carolina and discusses control measures.
Like other perennial plants, mature grapevines have extensive root systems and therefore, unlike shallow-rooted annual plants, they are fairly tolerant of mild droughts. Nevertheless, a certain amount of moisture is necessary to support growth and development. Lacking sufficient moisture, vines will suffer water stress, which can reduce productivity as well as fruit quality. Supplemental moisture can be provided by permanent (solid-set) or temporary irrigation systems. Drip irrigation has become the standard water delivery system for North Carolina vineyards in recent years. Drip irrigation can represent a substantial investment (see chapter 2 for details), but the benefits can far outweigh the costs in many vineyards. In 2005, it was estimated that drip irrigation would cost $22,743 to purchase and install the equipment required for a 10-acre drip system, or $2,274 per acre. Drip irrigation can be as effective on steep slopes as on rolling and flat surfaces.

Although subsurface drip irrigation (SDI) is in its infancy in North Carolina, it is becoming more popular as growers learn of its many benefits, which include increased irrigation efficiency. Proper management is imperative with an SDI system. Many components of an SDI system are underground; therefore, you must carefully monitor pressure and flow rates to ensure that the system is operating properly. This publication addresses water management, chemigation, system management and maintenance, and system evaluation.

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.
High-quality wines — those that command premium prices — can be produced only from high-quality grapes. Grape quality can be defined in various ways, but ripeness and freedom from rots are two of the chief qualities. Producing ripe fruit with minimum rot and maximum varietal character is not easy in North Carolina. As described elsewhere in this publication, the combination of climate, soils, and vine vigor often leads to excessive vegetative growth. For reasons that will be discussed, luxurious vegetative growth can reduce vine fruitfulness, decrease varietal character, degrade other components of fruit quality, and hamper efforts at disease control. Canopy management practices can help alleviate these problems.
