In Washington D.C., the best time to prune most trees is during late winter to early spring, before new growth begins. Pruning during this dormant season helps trees heal quickly, reduces stress, and lowers the risk of disease or pest infestation. 

In Washington D.C., some of the most common tree pests and diseases include Emerald Ash Borer, Mites, and Beech Leaf Disease. Here are signs and symptoms of how these pests and diseases can affect your trees. 

• Emerald Ash Borer: Attacked trees show canopy thinning, branch dieback, and bark splitting, starting in the upper canopy and progressing downward over several years.
• Mites: Signs that mites are present include spotting, bronzing, or yellowing of leaves and small webs between twigs.
• Beech Leaf Disease: Dark striping or banding between leaf veins, giving the foliage a distinctive look. These stripes can be seen in the spring at early leaf-out.

A Plant Health Care (PHC) Program is a proactive, year-round plan to keep your trees and shrubs healthy and pest-free. Our certified arborists focus on prevention and early detection by monitoring soil health, nutrients, insects, and disease. Based on your property’s needs, we create a customized care plan that may include fertilization, pest management, pruning, and soil improvement.
