Plant Those Cool-Season Crops!

News Article

Now is the best time to get out in your garden and plant cool-season vegetable crops. A cool-season crop is defined as a vegetable that grows best with temperatures of 60 to 65 degrees F. Cool-season crops can tolerate light to moderate frosts, but are intolerant of high summer temperatures. Listed below are common cool-season crops and their recommended spacing between plants and rows. Direct seeding of most cool-season crops can be done with the exceptions of broccoli, cabbage, cauliflower, and Chinese cabbage which would be better started by transplants.
