Does anyone know a way to fix curly leaf on my tomato plants?

Answer 1

you cant fix it. sounds like a fungal or air born disease. clean up all diseased part of the plant and around the plant and burn them. keep area around plants clean. do not compost diseased parts.

Answer 2

Clint's answer sounds right. If the lower leaves are the ones that are affected it is probably a fungus in the soil. During heavy rains the water splashes up and deposits soil on the lower leaves. Mulching with straw will keep the splashing from disturbing the soil. Staking the plants and pruning suckers will encourage air circulation and dry the leaves faster and slow the fungus growth. All diseased leaves must be removed so the fungus doesn't spread up the plant. Don't plant tomatoes in the same spot for three years or you will continue to have the same problem.

Answer 3

It could be any number of causes most of the links below have a photo associated with the disease.
