Leaves on tomato plants

Question

The leaves on my tomato plants are curling. I water them every evening and have tomatoes on all my plants. Do they possibly need vitamins? I live in northern Idaho, can’t remember the zone, sorry.

Answer 1

It is very possible that the weather is the cause of this, but it is also possible that it is tomato leaf curl (which can affect other nightshade members as well, like potatoes). If it is the weather, it will clear up on its own, but if it is tomato leaf curl, there may not be much you can do.
