Thanks fritz, it has been a good year.
Some thoughts:
A spring warm snap raised soil temperature significantly in the 3 weeks before my average last frost date. The plants I put in were huge and had been repotted 2 times prior to being planted. Big plants + warm soil = early growth and flowering (my theory anyway.)
Mid april is my average last frost date so the plants have been in for about 100 days.
It wasn't a damp june like last year when disease spread easily and the plants lagged due to few sunny days.
Every tomato plant was grown in soil mix that had never had a tomato (or potato) plant growing in it before. This gave me pretty much a disease free plot starting out. I did have one plant get swamped with a black fungus but I immediately pulled and destroyed and dodged a bullet.
Small = More. Roma VF was chosen due to fair disease resistance and a reputation for being prolific. It hasn't disappointed, with the 16 main plants putting out over 85 each on average, but remember these are 2-3 ounce paste & sauce tomatoes.
I can't keep up with the tommie toes at this point- I have two gargantuan plants that are now putting out dozens every day. They actually have a function in the garden I didn't expect though; ever since the birds figured out I was serious about netting up the bigger varieties, they gave up mostly and moved to the tommie toes. In this case, there are enough for all of us.
