I live in the Shenandoah Valley and last year I planted my tomatoes in late June. I didn't really get a substantial harvest until September but was picking tomatoes until Halloween (late frost helped!) I still have sauce in my freezer from last years harvest.
This year I planted May 31 - June 2 and have already begun harvesting. Most of what I plant are late season (85+days).

I am so jealous of the people who have already yielded pounds of tomatoes. I guess on the other hand though, in October they will be jealous of me! lol.

Well, it's a comfort to see I'm not the only one who planted late! Misplaced my long-awaited Ramapo seeds and was just too busy to get thr rest started on time. Picked up a seedling at a supermarket so I'd at least have something ... which I don't anyway because something's been tasting them before they ripen! A volunteer popped up in the poorest soil out by the curb - transplanted it to the veggie garden and it's developing a nice little crop of yellow pear tomatoes. The late-started seeds don't even have flowers yet, so I'm despairing of ever harvesting tomatoes from them this year ... unless I move them into my little greenhouse and invest in the supplemental lighting they'd need.

Oh, for just one tasty, tangy, home-grown tomato this summer.
