Me too with the San Marzanos. Had one plant with over 40 tomatoes. Like long bunches of grapes - they were beautiful and delicious. Last year we had 12 or 14 plants, this year about half. Also growing better boys and camparis.
Aren’t they lovely tomatoes? I’m very excited I found those seeds. 25 seats was very expensive, but now I just harvested my own and I have hundreds and hundreds.
They don’t taste quite like I wanted, not like the certified tomatoes that were actually born and raised with volcanic ash from mount Vesuvius . I actually did try using some of my woodstove Ash, lol,OK still not the right soil :-). I like the way I can both eat them and canned them. And the plants are determinit -How do you spell that –so short stakes are fine. I actually just go grab sticks from the forest, very economical :-)
This is the first time I’ve grown San marzanos. They do have groups of large grape like green matoes hanging down.
