Has anyone Had trouble with Tough Boy Hybrid tomato plants?
This year I decided to try Tough Boy hybrid tomato plants. They don't want to grow and the leaves are curled and small. Are they disease prone? What can I do?

They are actually bred to be disease resistant. If you planted early, and the weather has been crazy there (as it has in most of the US), the alternating cold and hot weather could just be making it a bit timid and it will start to grow once warm weather settles in.
There are also a few other things that could be causing the curling. This article may help:
