The Q&A Archives: Tomato plant leaves

Question: I have white

Answer: The white lines you see are probably from leaf miners. These little pests feed on the tissues between the upper and lower surfaces of the leaf. When they mature they will tunnel a little hole and escape from the leaf. Generally leaf miners do not reduce the number of tomatoes a tomato plant produces and are therefore left alone. To prevent an outbreak next year, be sure to clean all the debris out of the garden before planting next year's crop.
