Answer: There are several possible explanations. One is that you may be overwatering. The soil only needs to be moist like a wrung out sponge, not sopping wet or saturated. OVerwatering can cause root damage that then shows up as foliage problems and prematurely fading flowers. The second problem is too much sunshine. Hydrangeas prefer morning sun, which is less intense than afternoon sunshine. You may want to consider moving your hydrangea to another part of the garden - one that receives shade from hot afternoon sunshine. Best wishes with your hydrangea.
