|Growing Pears in Virginia||
Pears are the second most important deciduous tree fruit after apple, and it has been grown in Europe since prehistoric times. Pears belong to the genus Pyrus and probably originated near the Black and Caspian Seas. French and English colonists brought pears to America and the first record of pears in the North America was in Massachusetts in 1630. Although pear is a popular fruit, it is not grown as widely as apple. Pears can be grown throughout much of North America because they tolerate a wide range of climatic conditions.

|Growing Cherries in Virginia||
Cherries are grown in many parts of the world, but they have never gained the popularity in North America that they have in Europe and the Middle East. Cherries probably originated in the region between the Caspian and Black Seas, where trees still grow in the wild.
|Feb 26, 2015||422-018 (HORT-166P)|
|Growing Peaches & Nectarines in Virginia||
An orchard is a long-term investment and careful planning is essential to ensure economic success. Establishing and maintaining a peach planting to bearing age (three years) costs about $3,500 per acre. Mistakes made at planting often cannot be corrected; other mistakes that can be corrected could seriously jeopardize the economic success of the orchard. Because profit margins for commercial fruit plantings are small, orchards should be established only under the most favorable conditions for success.
|Feb 17, 2015||422-019 (HORT-96P)|
|Pruning Peach Trees||
Annual pruning is a critical management practice for producing easily harvested, heavy crops of high quality peaches. However, pruning is not a substitute for other orchard practices such as fertilization, irrigation, and pest control. Pruning practices vary slightly in different regions of the United States, but have changed little in the East during the past 70 years. Although pruning may vary slightly for different varieties and localities, certain general practices should be followed. The successful pruner must understand the principles of plant growth, the natural growth habit of the tree, and how the tree will respond to certain types of pruning cuts. Improper pruning will reduce yield and fruit quality.
|Jan 28, 2015||422-020 (HORT-93P)|
|Training and Pruning Apple Trees||
Proper training and pruning of trees is a major component of a profitable apple orchard operation. Successful pruning is an art based upon scientific principles of tree growth and physiology and an experienced understanding of tree response to various pruning cuts and practices. Each tree is an individual and should be treated accordingly. Varieties differ in growth characteristics and response to pruning cuts, rootstocks, soil, and growing conditions. It is important that orchard designs, objectives, and goals be clearly defined and that pruning principles are developed accordingly. Mediumto high-density plantings require greater commitment to detailed training and pruning than low-density orchards and should not be attempted unless such a commitment is made.

|Growing Apples in Virginia||
Growing apples in the home garden can be an enjoyable and rewarding experience, but consistent production of high quality fruit requires knowledge of tree and fruit growth and a willingness to perform certain practices at the appropriate time. Virginia is on the southern fringe of the U. S. apple producing region. Most apple varieties produce the highest quality fruit when night-time temperatures are cool (less than 60°F) at harvest time. Apples grown under warmer conditions tend to be large, soft, poorly colored, and less flavorful than when grown under cooler conditions. Our warm humid summers are also conducive for infection of many diseases. For these reasons, the best Virginia apples are grown at elevations higher than 800 feet above sea level in the western part of the state. However, even apples grown in eastern Virginia usually have quality superior to apples purchased in the supermarkets.
|Feb 16, 2015||422-023 (HORT-95P)|
|Training and Pruning Apple Trees in Intensive Orchards||
Since the mid 1970s in the U. S., the number of apple trees per acre in new orchards has gradually been increasing. Orchard intensification is motivated by the desire to produce fruit early in the life of the orchard to rapidly recover establishment costs. Intensification is possible by using dwarfing rootstocks that control tree size, induce early cropping, and produce large quantities of fruit relative to the amount of wood produced.
|Feb 24, 2015||422-024 (HORT-99P)|
|Physiology of Pruning Fruit Trees||
Woody plants are pruned to maintain a desired size and shape and to promote a certain type of growth. Ornamental plants are pruned to improve the aesthetic quality of the plant, but fruit trees are pruned to improve fruit quality by encouraging an appropriate balance between vegetative (wood) and reproductive (fruiting) growth.

|1995 Apple Variety Evaluations||
There are more than 2,000 apple varieties and new varieties are becoming available each year. Some apple varieties perform optimally under specific climatic conditions. Therefore, varieties must be evaluated in many geographical locations to determine adaptation to local conditions. Results from one such evaluation trial are presented in this bulletin. Fifty apple varieties on the dwarfing rootstocks M.9, MARK, or M.26 were planted in 1986 or 1988 near Blacksburg, Virginia. Blacksburg is located in the Allegheny mountains at 2,200 feet above sea level. All varieties were evaluated for at least three years.
|Feb 24, 2015||422-760 (AREC-130P)|
|1988-1995 Apricot Variety Evaluations in Virginia||
Many apricot varieties are available to tree fruit producers. Therefore, growers should become acquainted with characteristics of various varieties grown under Virginia climatic conditions. Currently, apricots are not produced commercially in the mid-Atlantic area because trees bloom early and are susceptible to spring frost. Flower buds are quite resistant to low winter temperatures and there are active apricot breeding programs in Ontario, New York, West Virginia, New Jersey, and Arkansas, as well as in California. If late-blooming productive varieties are planted on the most frost-free sites, and bloom delaying techniques are employed, Virginia fruit growers may be able to profitably produce limited acreages of high-quality apricots.

|Peach and Nectarine Varieties for Virginia||
Peach and nectarine are both members of the genus and species Prunus persica, and probably differ by only a single gene for skin pubescence (hairs on the fruit surface). One probably originated as a mutation of the other, but we do not know which came first. The species originated in China and was taken by traders from there into Persia, Greece, Italy, and other temperate areas of Europe. Peach and nectarine varieties may have yellow or white flesh. In Virginia different varieties ripen over a wide range of dates, from early June until mid-September. Varieties also differ in fruit size, susceptibility to some diseases and susceptibility to low winter temperatures, chilling requirements, and fruit disorders such as fruit cracking and split-pit. Descriptions of some of these characteristics are included in the next section of this publication.

|Urban Water Quality Management–Residential Stormwater: Put It in Its Place. Decreasing Runoff and Increasing Stormwater Infiltration||
Humans and plants depend on an adequate supply of clean water for a number of reasons, from producingfood to sustaining life. The average Virginia resident uses 826 gallons of fresh water daily (Virginia Department of Environmental Quality [VADEQ] 2008). In the Commonwealth alone, there are more than one million households that depend on well water, withdrawing more than 50 billion gallons annually (Virginia Department of Health 2008). For groundwater replenishment, we depend largely on recharge (water moving from the surface to groundwater) from infiltration of precipitation through permeable surfaces in the environment — an important part of the natural water cycle (VADEQ 2010).

|Gardening & Your Health, Carpal Tunnel Syndrome||
Gardening with carpal tunnel syndrome (CTS) can be very difficult, especially when a long day of shoveling, raking, or weed pulling leaves you with a painful or “tingling” hand or wrist. These aches and pains are often caused in part by improper techniques or tools used in gardening.

|Gardening and Your Health: Sunburn & Skin Cancer||
Most people have suffered from at least one bad sunburn. The beginning of a sunburn is shown by hot, pink skin. Later comes swelling, burning pain, and possibly blistering. As the burn leaves, peeling inevitably appears. Peeling means that the skin is thickening up to protect itself from further sun damage. If burned skin continues to get exposed to sun, damage can’t be repaired. Even if damage is not visible, skin cells mutate with each sun exposure. Over a lifetime these mutations may add up to cancer, a problem seen on gardeners who work unprotected in the sun. A severe sunburn is one of the biggest risk factors in getting a melanoma skin cancer.

|Gardening and Your Health: Plant Allergies||
Allergic reactions are caused by an overactive immune system response to a foreign substance such as pollen, dust, or molds. When this reaction affects the eyes or nose, it results in allergic rhinitis. Typical symptoms include sneezing, a runny nose, and itchy watery eyes. When an inflammation affects the bronchial tubes, it results in asthma. Typical symptoms include wheezing and shortness of breath.

|Planning the Vegetable Garden||
How much time will you be able to devote to your garden on a regular basis? The answer to this question will dictate the size of your garden. You must remember that, once planted, the garden will have to be weeded once a week, irrigated during droughts, and vegetables harvested when ripe. Depending on the type of vegetables, you may also need to undertake pest control measures.
|Dec 11, 2015||426-312 (HORT-209P)|
The ideal soil for a vegetable garden is deep, friable, and well-drained with a high organic matter content. Proper soil preparation provides the basis for good seed germination and the subsequent growth of garden crops. Careful use of various soil amendments can improve garden soil and provide the best possible starting ground for your crops.

|Leafy Green Vegetables||
Lettuce, a cool-season vegetable crop, is one of the easiest to grow. Lettuce withstands light frost; however, sunlight and high summer temperatures usually cause seedstalk formation (bolting) and bitter flavor. Slow-bolting or heat-resistant varieties are available and are recommended for extending the lettuce-growing season.

|Onions, Garlic, and Shallots||
Onions are often grouped according to taste. The two main types of onions are strong flavored (American) and mild (often called European). Each has three distinct colors, yellow, white, and red. In general, the American onion produces bulbs of smaller size, denser texture, stronger flavor, and better keeping quality than European types. Globe varieties tend to keep longer in storage.

|Getting Started in the Production of Field-Grown, Specialty Cut Flowers||
Specialty cut flowers are one of the most profitable field crops you can grow. Lynn Byczynski, editor of Growing For Market newsletter (see Resources section), estimates a value of $25,000 to $35,000 per acre for field-grown cuts. The most basic requirements are at least half an acre of open, arable land, a rototiller, and, of course, time and effort. This publication is directed to those new to market gardening, but commercial vegetable growers, tobacco farmers, and young people interested in summer income are all potential candidates. Even grain and livestock farmers have increased profitability in their operations by adding cut flower production. For many greenhouse and nursery operations, mid-summer business is slower, relative to spring. A field-grown cut flower business is a viable option to fill in the summer production and cash flow gap.

Containers differ from raised planters in that they are usually smaller in volume and moveable, whereas planters are generally larger, and often built as part of the permanent hardscape (paving, etc.). The greatest challenge in selecting trees for containers and planters is in choosing trees that can survive temperature extremes, and that can establish roots in a limited volume of substrate (potting soil). Consider several factors when selecting containers and trees including environmental influences, container and planter design, substrate type, and tree characteristics.

|Trees for Problem Landscape Sites — Trees for Hot Sites||
Hot landscape sites require special consideration before trees are planted. Trees can survive, and even thrive, in hot sites if the site is prepared correctly, if heat-tolerant species are selected, and if the trees are properly maintained. A variety of different locations and situations qualify as hot landscape sites.

|Trees for Problem Landscape Sites — Screening||
Using trees as living screens can easily enhance living and working spaces. Before selecting trees for screening, first determine the screen’s purpose, whether functional or environmental. Screening can be used to define an area, modify or hide a view, create privacy, block wind, dust, salt and snow, control noise, filter light, and direct traffic flow.

|Trees for Problem Landscape Sites — Wet and Dry Sites||
To grow, all trees require air, light, water and nutrients. Some trees can survive over a wide range of climatic and soil conditions, whereas others are very site specific. Both wet and dry sites present establishment and growth challenges, making selection of the right tree for the right site very important.

|Trees and Shrubs for Acid Soils||
The trees and shrubs on your new home site are growing poorly, so you take samples to the Extension office and the agent suggests a soil test. Test results show that your soil has a pH of 4.5, which is rated as strongly acid. The agent suggests you either take corrective action to raise the pH or grow different plants. What do the test results mean? What are “acid soils” and what does pH measure? Why does this matter to your plants? How can you correct the situation or what alternative trees and shrubs can you grow?

|Specialty Crop Profile: Asparagus||
Asparagus, (Asparagus officinalis), is a hardy perennial vegetable belonging to the Lily Family. It is grown for its succulent early spring vegetative shoots that originate from an underground crown (Figure 1). Nutritionally, asparagus is almost 92 percent water, and it provides fairly high amounts of carbohydrates, vitamin A, riboflavin, niacin, thiamine, and phosphorus. A native of coastal Europe, asparagus has naturalized over much of the eastern United States. With the assistance of man and birds that have spread the seeds, asparagus can be found in gardens, old homesteads, fencerows, roadsides, and railroad right of ways across the state. It is well adapted to most of Virginia, preferring well-drained loam soils and easily tolerating winter cold and summer heat. Asparagus is long lived, and a well-managed planting can last 10 to 15 years. For those considering it as a potential crop, good planning and soil preparation are essential for long-term success.

|Guide to Identifying Food Safety Hazards in Greenhouse Systems||
According to the United States Department of Agriculture 2012 Census of Agriculture, sales from greenhouse-grown food crops equaled around $800 million in the U.S. Crops grown included tomatoes, lettuce, cucumbers, peppers, and berries, with hydroponic production operations making up about 64% of the total production (cwt) (USDA Census of Agriculture, 2012). Demand for greenhouse-grown produce continues to increase, providing growers with unique opportunities to tap into this expanding market. Although greenhouse systems provide a more protected environment than field-grown systems, it is important to understand the unique food safety risks and possible sources of contamination when growing produce in these systems. Identifying food safety hazards are necessary to implementing practices that reduce the risk of contamination during the pre-plant, production, harvest, and post-harvest handling stages. Use the checklist below to guide you in asking important questions targeting possible risks at each of the greenhouse system stages.

Plant growth regulators (PGRs) are chemicals that are designed to affect plant growth and/or development (figure 1). They are applied for specific purposes to elicit specific plant responses. Although there is much scientific information on using PGRs in the greenhouse, it is not an exact science. Achieving the best results with PGRs is a combination of art and science — science tempered with a lot of trial and error and a good understanding of plant growth and development. good understanding of plant growth and development.

Gardening is a great activity to help maintain physical and emotional well-being. However, it is not without its challenges, even for the able bodied. With a little creativity, gardening can be an accessible activity and can have therapeutic value. As a therapy, gardening is unique in that a living medium, plants, are used. This allows the gardener to be anchored in reality. When gardeners realize that they have an effect on something else that is living there are often positive changes in their behavior and feelings. The term therapeutic gardening means that the activity of gardening is designed to assure positive health outcomes and minimize negative outcomes.
