My tomatoes won't turn red
I'm in Minnesota.
We've had a very mild summer, a bit hot at times, but not consistently. I've had a bunch of large green tomatoes on the vine for weeks, but they just won't turn red. We've got a few other plants growing in a hanging basket that have put out a few red ones, but the plants in our garden won't redden up!
I'm really at a loss. Frustrated. The plants seem to have some sort of constant wilt. The leaves are thicker and greener than most tomato plants I've seen. I've been watering them like crazy but that doesn't seem to make a difference. They just get droopier and the tomatoes all stay green. Some of the lower leaves are curling and/or getting yellow spots!
What do I do?
Any help is GREATLY appreciated!
