Curling Leaves on Tomato Plants

All of our tomato plants' leaves are curling under. They are producing tomatoes like crazy, though. We fertilize them with Miracle Grow -- don't know what's up with them.

Anne's Response:

Curling leaves on tomato plants can come from uneven watering - especially too much water. It is also caused by insect damage - especially spider mites and aphids. You can usually see signs of insect damage on the back of the leaf. Washing the insects off the back of the leaf with a strong stream of water from a hose is one safe way of taking care of the problem. You may need to add some lime to the soil to counteract the acidity of a lot of nitrogen fertilizer from the Miracle Gro.
