My rhododendron/azalea has seemed happy since I brought her home a few months ago. It has a lot of new growth. It’s been in the same spot, indoors under plant lights and north window lighting. Recently the older leaves have started developing yellow veins and falling off in large numbers. I am planning to repot her in a mix of course perlite and high quality organic potting soil. The pot is very small compared to the foliage and it’s in some sort of solid spongy organic material. She has a few spider mites but I am managing them. They aren’t on most of the leaves that fall off and I don’t think they’re numerous enough to be stressing the plant too much. No webbing yet. Any help would be appreciated! I don’t want to lose her.
