Question: My tomato plants’ leaves are pointed and very odd looking. In fact, you would hardly recognize them as being tomato foliage. What causes that?

Answer: Usually they have been hit by a drift of a broadleafed weedkiller. No plant that you grow will be any more sensitive to this entire category of garden products. Be especially careful when you treat for dandelions, poison ivy, clover and other non-grassy weeds if tomatoes are growing anywhere nearby. There is nothing you can do other than to wait and see if the plants outgrow it.
