Tomatoes WILL NOT RIPEN above 90 degrees, in most places. They will stay dormant during the hot days and do their growing at night.
I live in S. Utah, six miles from the AZ border, so I have learned this the hard way.
I don’t think they will put on new tomatoes when the temps go over 90. Not one of the new blooms has set lately.
Try this:
Remove a lower “branch” from your tomato plant. Pot it up in a five gallon container. Remove all the leaves from the roots until you’re about at the 2” mark of the plant’s height. At this point, you’ll start to believe I’m nuts and you were stupid to read this post. LOL
Tomato plants are one of the few that will root anywhere the plant meets the soil. There is no such thing as planting a tomato too deep. Use a good potting mix, water it well, and put it in the shade. On the north side of your home, if it’s still 100 degrees.
You’ll see the difference and thank me later. And you’ll have some tomatoes!
When it starts getting back to 80 degrees each day, you can put those pots in the sun.
But not until then.
