In North Philadelphia, 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 North Philadelphia, some of the most common tree pests and diseases include Emerald Ash Borer, Dogwood Anthracnose, and Apple Scab. 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.
• Dogwood Anthracnose: Tan, blotchy leaf spots are early signs of infection, which can lead to dead leaves and twigs remaining attached to the tree.
• Apple Scab: Olive-green to black velvety spots appear on leaves, sometimes causing yellowing and early defoliation.

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.
