What a change from last year! Starting April with snow is one thing. How about these other interesting differences year to year. This March ends with 12 Growing Degree Days (GDD’s) where last year ended with 20 GDD’s. So it has been much cooler (with the exception of March 18th). And much drier, Last March ended with over 14 inches of rain, this March just under 2 inches of rain. This will be a slow start for insect pests, such as the winter moth which needs 20 to 50 GDD’s to hatch. -Lauren Greenhow, General Manager, GreenHow, Inc.
