In Dulles, 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 Dulles, some of the most common tree pests and diseases include Spotted Lantern Fly, Mites, and Lace Bugs. Here are signs and symptoms of how these pests and diseases can affect your trees. 

• Spotted Lantern Fly: The most noticeable symptom is wilted foliage, which can affect the entire tree in severe cases. The trunk may develop open, oozing wounds that secrete a sticky, sugary substance.
• Mites: Mites, though nearly invisible, cause noticeable damage to trees, shrubs, and plants. Signs include leaf spotting, bronzing, yellowing, and small webs between twigs.
• Lace Bugs: Infestation signs include bleached leaves, premature leaf drop, and shiny black excrement on leaf undersides. Unlike spider mites, lace bugs do not produce webbing.

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.
