My hydrangea has some drown deying leafs and they look like they also have some white on the leafs there in pots write now with Good drainage what amounts I doing wrong?
It sounds like they are winding down for the season as the days get shorter. The white may be powdery mildew, a fungal disease…rarely does permanent damage. Keeps the leaves dry when watering….spray watering encourages fungal disease like powdery mildew. For a more accurate assessment, bring the plant or leaves from the plant to one of our garden centers so they can see exactly what the problem is.
