Here we can plant cold crops like cabbage and broccholi in the spring and harvest the broccholi by mid summer, then replant broccholi for a fall crop. Chard and spinach for a fall crop as well and we can usually get away with with harvesting into November unless the fickle finger of fate (snow) happens earlier than expected. I usually provide some protection for my greens but right now we are having a bumper crop yield of tomatoes, beans, summer squash and cukes. Keeps me busy and you what waht they saw about idle hands!
