The Q&A Archives: Why Tomato Seedling Leaves Turn White and Die

Question: Within three days of planting my tomatoes, the leaves turn white and transparent. In about a week the plant breaks in half and dies! What am I doing wrong? Joe Conway Warminster, PA

Answer: You probably didn't harden off the plants well before putting them out. The leaves turn white when sun burned. Before putting plants out, slowly expose them to the sun and wind by putting them out for 1-2 hours the first day and gradually increase thetime out by a few hours a day until they can stay out all day and night long. The white areas will eventually brown and dry, but the new, young growth will replace it once the plant gets going.
