Here is your Growing Degree Day (GDD) summary ending March 31, 2022. While the calendar says it is spring, our actual outdoor experiences made have said otherwise. We have enjoyed some spring-like temperatures, but on the flip slide, snow flakes have been flying in the not so distant past. Hopefully now that it is officially April things will change - who are we kidding, it is Ohio.
Stay tuned for these year-to-date summaries each month in 2022.
