Today, in preparation of this years growing season, I’ve made a new graph for my growing season. This time i averaged the weather data (cooling data from http://www.degreedays.net/) from 2010 and 2011. The result on a 60F base shows a really accurate and nice graph for my growing season. According to this data it looks like i could plant cool-season crops from March 15th – May 10th if i wanted to. It also shows that for everything else (like corn and watermelon) it’s probably best to plant on or around May 10th, since the heat takes off after that.
