I have a First Edition Berry White Hydrangea. It’s new and was planted last fall and has beautiful blooms. But it keeps losing leaves. They turn…sort of a very dark yellow…but more brown, really and fall off. It have it on a drip system so I can adjust how much water it gets. I live in Zone 7 and it’s over 100 each day right now, so I am giving the plants on my drip about 20 mins. of water a day. Not sure what to do? It is getting too much or note enough water?

I have four Endless summer hydrangeas that are about 5 years old. Planted in various areas of sun to partial sun in our yard. I rarely get blooms. This year I got one bloom of all four plants. I cut them down in the fall as I thought this was the variety that bloomed on new wood. Is this the problem?
