What should I plant for the fall? Or is it too late to get going on it?

Check your growing season. When is your expected first frost. Some plants are minimal 55 to 65 days,but most fruiting crops are 70 or greater. if you dont have that much time, then about all you can plant is ground crops and greens. radishes, turnips, kohlrabi, .... Might get some new potatoes in if you plant NOW...Snow peas, possibly, try pac choi, chinese cabbage, kale, mustard, .... just check your growing season and your maturity date on the package....
