Iron deficiency or chlorosis or overwatering can cause hydrangea leaves to yellow. Chlorosis occurs when a plant is unable to take in enough iron because the pH of the soil is too high. Check the pH of your soil. If it is above 6, consider lowering it with Yates Soil Acidifier, Yates Hydrangea Blueing Tonic or apply Yates Iron Chelate . Lengthen the time between watering if overwatering is the issue.
