We don’t have luck with large tomatoes either. Too hot. Just Roma and Cherry tomatoes will do well. Thanks for the tip. I’ll try it.
You will be surprised at how pleasing a fresh picked tomato can be, in the middle of winter, LOL, it is worth every minute of bother.
And the kids will get to see them grow and ripen, close up.
I know when I have them in the house, I watch / check them daily.
