I'm probably asking a very obvious question here, as I'm a newbie to veg gardening, really. Certainly never come across this before.
We have three tom plants in a growback, against a brick wall. We do it every year, always works a treat. But this year one branch on one plant has gone quite weird. The leaves are all curled over and limp, and growth is stunted. In two or three weeks this has stayed local to the same branch, it has not spread at all. We're further north than a lot of you, hence no fruits yet - our flowers are just starting to come now.
