Is there a university website that updates the current soil temp throughout the ohio-ind region. Once the calendar hits April the phone will go crazy saying WE ARE TOO LATE to apply crabgrass control. I know I can use my own soil gauge. However, I would like to direct the homeowner to a University site so they know the temp is still colder thaen they think----Thanks
That may be true but the forsythia are close enough. Ohio State University has a website for "degree days" which has a low list of bloom times of various bushes and trees coupled with when certain pests hatch or weeds germinate.
I would refer you to it but it's only for Ohio. Maybe your university might have something similar. Maybe you can checkout "degree days."
