I have 8 tomato plants that are about 3 foot tall and are covered in blooms and a few tomatoes. They were doing fine until about 2 weeks ago when I noticed the two Cherokee tomatoes started wilting on the top. It has been a hot and dry spring so I was watering them about every 3 days at night. Then a week ago it cooled off and rained for 4 days and we got about 5 inches of rain.

It looks like someone has poured hot water on them. They are not turning yellow and have no blemishes on them. I pulled one up and the roots look good and the soil was not soggy. I know the other 4 plants I have down the row from them are starting to wilt on the top. I sprayed them with a fungi spray. I do have a few large black walk nut trees about 20 feet away. Please help.

Water and mulch them so the water doesnt evaporate.

I have had the same problem with my one plant I made a hot house for. It was hot and dry in May and I pinched off the suckers. I just read that heavy pruning in hot weather can cause the leaves to curl.

I do have some large healthy looking tomatoes on that plant that I'm expecting to get ripe soon. However, now we are having cool, wet weather so I don't know how that will affect the tomatoes.

We needed the rain but not all at once. Crazy weather we are having.
