This Rhododendron Didn’t Flower This Year And The New Leaf Buds Have Now Curled Up And Gone Brown.

Question

I bought this plant last year and it flowered beautifully. This year it seems to be suffering from something. If it needs to be moved should I do it now before it gets any worse?

Answer 1

Is it planted in a shady location with rich, acidic soil? If not, consider moving them. Also check the pH level of the soil. It is important that it be betweeen 4.5 and 6.0. A high pH can cause yellowing leaves.
If those check out, look for insect problems such as spider mites or lace bugs. This article will help:
