Pests alerts

Information provided on this page is far from an exhaustive list of all the diseases, pests, environmental stressors, and other factors that may diminish tree health. It’s our hope that these resources will serve as an introduction to present and emerging threats that trees in Novi may face.

A good first step toward diagnosing potential problems is knowing what species of plant you’re examining, as many diseases or pests specifically affect just one or a small handful of species.>/p>
