Yep, agreed that you would probably be better off putting energy into growing more season appropriate stuff in summer. I have some lettuce growing indoors this time of year but the only greens still surviving outside are the rare swiss chard and then stuff that most people don't think of as greens so much. Like the young leaves and vine tips of southern peas and other related bean varieties. There is also stuff like malabar spinach and new zeeland spinach if you like them. The young leaves and vine tips of sweet potatoes are also edible. Truth is, my system in the central Florida heat tends to give over to things like bananas, basil, oregano, sweet potatoes, Okra, yardlong beans, papaya, stevia, and heat loving flowers for the months of July and august. Even the tomatoes give up in the heat.
TCL, Are you growing your Stevia in an AP system or in some other fashion? What variety is it? Also, I think I seen another post somewhere about you growing Purslane... same questions as above. Thanks
