I've tried to plant early or late, determinate or indeterminate. But, with the exception of cherry, I can't extend my harvest beyond mid July to mid Sept. What is your experience?
My Frost Free season extends from 15 Apil to 21 November,and I usually plant out early and extra early tomatoes around the first of April and then again the first of August.
You should be harvesting tomatoes long after mine quit. What's your fertilizer regimen?
