It’s been a really cold winter. However, 
despite that, we had a couple really warm days last week. Because of that, we have already accumulated 7-9 growing degree days in Cincinnati and 5 in Columbus. Silver maple comes into bloom at 34 degree days. This week is the coldest week of the winter. After this, we begin to slowly warm toward the first day of meteorological spring. We are already 7-9 growing degree days closer!
