Hi, I bought a well established white hydrangea this summer which was going along quite nicely. Since returning from my holiday I've noticed the leaves have gone brown round the edges, the flowers are fine but not the leaves. Could it of been over watered?
Its in a spot that gets plenty of sun and I generally keep on top of watering that's why I thought maybe over watered??
If you've been away for a bit it is more likely to be that it hasn't had enough water (unless you've had someone coming in and watering). They don't like full sun much and generally grow better in spots with some shade.
They are thirsty things so it's good to read that you're watering it well.
