What causes plant leaves to turn yellow?
Usually the yellowing of plant leaves is caused by the inability of the plant to take up enough iron from the soil to keep the leaves green. This condition is worse when we have a lot of rain or water heavy. What is this yellowing called and what symptoms should we look for on the plants? We call this condition iron chlorosis. A sure fire method of distinguishing this condition from other problems is to examine the affected leaves closely. With iron chlorosis the leaves will be yellow but the veins in the leaves will be a greener color. What can be done to treat iron chlorosis? Iron supplements are available in both the liquid and powdered form. The liquid form when mixed with water works good on low growing plants and shrubs but has short term results. The powder which needs to be gotten down to the roots is slower acting but has longer term results.
