|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: Protecting Your Hands and Feet||
The skin on hands and feet is like most ornamental plants. Neither likes the extremes of being dried out or kept too wet. Treat skin as tenderly as the most sensitive plants and safeguard your horticultural health.

|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.

|Managing Winter Injury to Trees and Shrubs||
It is often necessary to provide extra attention to plants in the fall to help them over-winter and start spring in peak condition. Understanding certain principles and cultural practices will significantly reduce winter damage that can be divided into three categories: desiccation, freezing, and breakage.

|Growing Azaleas and Rhododendrons||
The spectacular spring flowers of azaleas and rhododendrons make them among the most popular garden shrubs. However, azaleas and rhododendrons are shrubs for all seasons. Throughout the summer and fall the leaves add a pleasing, deep‑green color to the garden. Some deciduous azaleas add bright fall color before the leaves drop. In winter, some varieties stand out with large, evergreen leaves.

|Selecting Landscape Plants: Rare and Unusual Trees||
There are many tree species that can be successfully grown in Virginia, but are rarely seen in our landscapes. Although not ordinarily recommended or readily available, these trees may be useful to carry out a specific landscape theme, to substitute for an exotic type which is not locally adapted, or may be prized for unusual form, flowers, fruits, bark, or foliage.
|Jun 18, 2015||426-604(HORT-107P)|
|Selecting Landscape Plants: Conifers||
Conifers, also known as narrow-leaved or needled evergreens, are planted primarily for the attractiveness of their evergreen foliage. The variety of sizes, shapes, and colors available contributes to their popularity. Conifers range in size from prostrate plants growing only a few inches tall to large trees. Shapes include flat ground covers; horizontal spreaders; upright, pyramidal forms; and even weeping and contorted forms. Foliage color ranges from a gold and cream variegation to all shades of green, gray-green, and blue-green.
|Apr 6, 2015||426-605 (HORT-108P)|
|Selecting Landscape Plants: Broad-Leaved Evergreens||
There are a large number of highly ornamental broadleaved evergreens. However, many of them require special attention if they are to develop into attractive, long-lived plants. Wide fluctuations in temperature, prolonged dry periods, drying winds, and bright sunshine are not ideal conditions for most broad-leaved evergreens, yet these conditions frequently occur in Virginia. Good soil preparation and a carefully selected location will help ensure the success of these plants. However, the year-round beauty and special effect that they give to the landscape make them well worth the extra care needed to grow them.

|Selecting Landscape Plants: Shade Trees||
Trees are the basic element for any landscape plan. They set the stage for the entire home grounds design. The type used and their location determine to a great extent what other plantings are appropriate. Providing shade usually requires tall, sturdy, long-living species. Density of foliage, which determines the amount of shading, is important. A tree such as a Norway maple will produce a very dense shade that prevents other plants from growing under it, while a honey locust will produce a light partial shade which is not a hindrance to other plants growing below it. Deciduous trees should be used to shade the south windows of a home in the summer, thus allowing the sun to penetrate in the winter.

|Fertilizing Landscape Trees and Shrubs||
Maintenance programs should be developed for trees and shrubs in both residential and commercial landscapes. A good maintenance program includes monitoring and controlling insect and disease problems, suppressing weed competition, and making timely applications of water, mulch, and fertilizer. Tree and shrub fertilization is especially important in urban and suburban areas of Virginia where soils have been altered due to construction. These urban soils tend to be heavily compacted, poorly aerated, poorly drained, and low in organic matter. Even where soils have not been affected, fertilization may be needed as part of a maintenance program to increase plant vigor or to improve root or top growth.

|Selection and Use of Mulches and Landscape Fabrics||
The term “mulch” refers to materials spread or left on the soil surface as protective layers, whether organic or inorganic, loose particles or sheets.

|Trees for Problem Landscape Sites — Trees for Landscape Containers and Planters||
Planting trees in aboveground containers and planters is becoming a common practice on sites that are not suited for inground planting. 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.
|Apr 9, 2015||430-025 (HORT-117P)|
|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?

|Trees and Shrubs that Tolerate Saline Soils and Salt Spray Drift||
Concentrated sodium (Na), a component of salt, can damage plant tissue whether it contacts above or below ground parts. High salinity can reduce plant growth and may even cause plant death. Care should be taken to avoid excessive salt accumulation from any source on tree and shrub roots, leaves or stems. Sites with saline (salty) soils, and those that are exposed to coastal salt spray or paving de-icing materials, present challenges to landscapers and homeowners.

|Getting Started in the Nursery Business: Nursery Production Options||
The nursery industry in Virginia has enjoyed an extended period of growth and expansion. Consequently, there is considerable interest in and some potential for new business opportunities in the industry. Another consequence of this period of economic growth is an increase in competition within the industry to supply the growing demand for landscape plants. Those interested in getting into the nursery business are strongly encouraged to invest their time and energy into learning as much as they can about the modern nursery industry, and the many options now available in nursery production, before they invest any money in facilities and operations.

|24 Ways to Kill a Tree||
Few residential trees die of “old age.” Mechanical damage and improper tree care kill more trees than any insects or diseases. Avoid making the tree-damaging mistakes shown in the diagram below. Few of these items alone would kill a tree, but multiple problems will certainly stress, and could eventually kill, a tree.

|Tree and Shrub Planting Guidelines||
Select trees and shrubs well-adapted to conditions of individual planting sites. Poorly-sited plants are doomed from the start, no matter how carefully they’re planted.
