There are about 30 on the plants & most are about tennis ball size or bigger.
The recent very hot & very cold spells killed off a lot of the tomato flowers though. 😕

You’re lucky you’re still getting some produce. I’ve got a part of one plant left with flowers still on it, but I think it’ll get too cold for them to do anything - I live in hope though🤣.
Just as an aside, if you don’t think the tomatoes you have on the plant will ripen - fried green tomatoes taste just as good as red ones.
