Each Tuesday, members of the Extension Nursery Landscape and Turf (ENLT) have a virtual meeting to discuss what they are seeing in their own area and talk about those "stumpers" that they have come across in the horticulture world and get feed back from others in the group.
The Growing Degree Day (GDD) range from callers was 124 (Toledo) to 256 (Cincinnati). Other accumulations included: 130 (Burton); 182 (Wooster); 206 (Springfield); and 221 (Columbus).
The GDD calendar is an awesome tool to help with horticultural happenings. If you haven't been using information from the GDD website, don't wait another moment. Check it out today: https://www.oardc.ohio-state.edu/gdd/
