While sitting outside this morning (in the stifling humidity…ugh), I noticed that some of the leaves on the rhododendron were turning yellow. From what I’ve been able to learn online, the yellowish leaves with green veins are most likely the result of a too alkaline soil. I knew that rhodies, like most evergreens, like an acidic soil, and intend to buy such a fertilizer this weekend.
I was so pleased at how much new growth this plant put out this summer and I want to nip any problems in the bud…so to speak. :) I’ve checked the leaves for mites and other critters, and found nothing. We have had some very hot days this summer, and rhododendrons do have a shallow root system, but we had enough rain that the soil stayed moist without being soggy.
If anyone can shed any further light on the situation, I’d be most grateful for any suggestions.
