Proactive Monitoring of Tree Pests and Diseases Tips
We are weeks now into the growing season, and our trees are starting to show their fresh green leaves, but, wait a minute, not all of the leaves have their pristine appearance. This often means damage to tree leaves and stems is the first sign of a bigger problem, usually in the form of an insect infestation. If you are seeing something odd on your tree, find out what the problem is before you start to treat it. Use our tree shrub service checklist below to pinpoint what the insect is, and how to stop it.
