Answer: Brown leaves can indicate over watering, especially if the leaves are still soft and pliable. If the leaves are crispy brown, they are probably sunburned. When you water your hydrangea, water deeply and then allow the top of the soil to dry out before you water again. If you keep the soil too moist it can suffocate the roots of the plant. Hope this helps you determine just what might be wrong with your hydrangea.
