With summer, comes less rainfall and potential drought conditions. The primary responses of a tree to heat and drought are a reduction in photosynthesis and carbon assimilation rates. This translates to a reduction in energy production and food reserves. This reduction can increase vulnerability to health issues and reduced defense mechanisms against pests.

For these reasons, it's important to take extra steps to care for your trees during the summer.

Water trees when there isn't adequate rainfall.
Refresh your mulch.
Look for signs of bugs infestation.
Prune only when absolutely necessary; Removing only dead wood. Wait to start pruning living branches until early fall.
Call in a professional; it is always a good idea to consult an ISA Certified Arborist for answers to tree questions.
