September is Louisiana’s last chance to plant a relatively diversified vegetable garden before next spring. During this month we can detect the first signs of cooler weather that accompanies the fall. There are some vegetables that can go in in October, but the list slims down.
We do have some limitations, however, in that it is still too hot for some crops and not enough time to harvest before frost. There are about two dozen crops that can be successfully planted this month. In the fall, choose quick-maturing cultivars to beat the frost.
South Louisiana may attempt bush snap beans and Irish potatoes, but it's too late for that in the northern parishes. Pole types and limas are past. You also can seed or transplant broccoli and brussels sprouts in the south, but north Louisiana should transplant only broccoli and sprouts.
All of the state may seed beets, cabbage, Chinese cabbage, carrots, Swiss chard, collards, turnips, mustard, endive, escarole, lettuce, onions and leeks (seed only), kohlrabi, parsley, English peas, radish and bulbing shallots. Seed rhubarb now for harvest in spring.
Now is the time to transplant green shallots and cauliflower. Hold garlic sets and spinach until October.
Fall can be dry, so pay attention to those seedlings and transplants with thin root systems. Contact an extension agent in your parish LSU AgCenter office to learn more about growing fall gardens.
