In Wilmington, 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 Wilmington, some of the most common tree pests and diseases include Dogwood Anthracnose, Emerald Ash Borer, Spotted Lanternfly. Here are signs and symptoms of how these pests and diseases can affect your trees. 

• Dogwood Anthracnose: Tan, blotchy leaf spots are early signs of infection, which can lead to dead leaves and twigs remaining attached to the tree.
• Emerald Ash Borer: Attacked trees show canopy thinning, branch dieback, and bark splitting, starting in the upper canopy and progressing downward.
• Spotted Lanternfly: Damage can cause wilted foliage, and in severe cases, widespread wilting and oozing trunk wounds. 

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. 

If you suspect your tree is infested with a pest, contact your local Davey office. Our arborists are equipped with the knowledge and tools needed to identify and treat pests, and to implement preventative measures to avoid future infestations.

Once heavy rainfall passes, perform a soil test to check the soil’s moisture levels. If it’s still soaked, avoid watering your tree until it needs hydration. Hold off on fertilizer until the soil drains and keep an eye out for signs of damage the next growing season. Read our blog to learn more about oversaturated soils. 

When conducting a visual inspection of your tree, start from the ground up. Look for heaving or severed roots, peeling bark, and decaying wood, and dead or dying branches and leaf deformities. Read our blog to learn how to tell if your tree is dying or dead.
