Trees and other green landscaping elements are some of your association's most valuable assets. In addition to providing all-important curb appeal, trees and shrubs provide privacy, act as windscreens, and prevent soil erosion. Taking care of your trees and other large plants is just as important as caring for your paved surfaces, roofing, or any other exterior element.
The impact of winter’s adverse weather on the health and survival of plants is difficult to predict. The current extreme drought conditions in New Jersey, combined with two very severe winters have presented a worst-possible-case scenario for all natural vegetation, and put enormous stress on suburban trees.
Trees struggling against root restriction, poor drainage and the subpar soil conditions that exist in many communities are particularly hard-hit. Frozen ground has inhibited the intake of water through roots, while at the same time, icy winds have accelerated the process of water loss (or “transpiration”) through leaves and stems resulting in a condition known as winterkill. The trees’ weakened condition is an open invitation to attracting rot, fungi, and a variety of insects. The degree of plant injury above and below ground may not be readily apparent, but the effects may be felt long into the future. Come springtime, many of your community trees will experience much slower growth while they rebuild their defenses.
Trees and shrubs that have suffered will definitely benefit from special care, including watering and maintaining adequate soil moisture, proper mulching, careful pruning, bio-fertilization and applications of Cambistat—a treatment that reduces canopy growth and redirects that energy to other parts of the tree's system, such as roots, defense and storage. A good root system is necessary for overcoming drought and winter stress, and early bio-fertilization will help encourage root growth and give your trees and shrubs a head start.
Early Preventive Maintenance
Trees and shrubs sleep in winter—and so do parasites. The early application of horticultural oil is safe for the environment and prevents over-wintering pests from attacking your trees and shrubs later in the season. The application of horticultural oil on woody plants to control a large variety of pests is not a new practice, but is one that has not been widely used until recently. In response to increasing public demand to reduce chemical pesticide use, refined horticultural oils provide a safer and more environmentally friendly method of pest management. They degrade quickly following application, are non-toxic to humans and wildlife and fit very nicely into a Plant Health Care (PHC) program.
