Tree Wellness Schedule
This schedule is designed to illustrate when our Tree Wellness Technicians treat plants/trees in Central Ohio. Why the schedule? Diseases/pests are only susceptible to treatments during certain time windows. For example: To treat a tree for a spider mite infestation, we need to apply miticide to the tree when the adult spider mites emerge. By using the below schedule, we see that the adult spider mites emerge on GDD 627 so we must treat trees on or very near that growing degree day. If we are too early/late, the treatment would not be effective.
Special Thanks to The Ohio State University for the amazing information provided in their GDD Calendar!
