The leaves of my tomato plants are curled, the stems have bumps and the lower leaves turn yellow and fall off. Is something wrong?
This describes a normal tomato plant. It is natural for the leaves of tomato plants to curl under. The bumps on the stalk are normal and many tomatoes have them. They are actually nodes and if the stem were placed in a glass of water roots would grow out of the nodes. The lower leaves of the tomato plant usually turn yellow and fall off as the plant grows up.
