Plant Those Cool-Season Crops!

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 60o to 65 oF. 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.

Vegetable Inches Between Plants Inches Between Rows
Broccoli 18-24 24-30
Cabbage 18-24 20-28
Cauliflower 18-24 24-30
Chinese Cabbage 12-18 20-24
