My rhododendron is dying
One of my rhododendron bushes turned brown and appears to be dead, since about mid August. Now other bushes in the group are turning yellow and dropping leaves. I checked the backs of the leaves to see if there are aphids but I can’t see any insect damage. Any advice?

We had record-breaking drought this summer. We still have a rain deficit of many inches. Water deeply.
All plants, but especially broad-leaved evergreens like rhododendrons, suffer damage and even death when they go into the winter in dry(ish) soil. Water well.
(Dropping some leaves in fall, even on evergreens, is normal. But this year, water will be the crucial factor to watch.)
