Rhododendron Leaf Problems

johncrthomasJanuary 4, 2013

I have a 3-year-old pink flowered Rhododendron
planted in my Kensington, MD garden. It is about
1-2 feet high. It has obvious leaf problems, but
I do not know if this is a pest, disease, or
cultural problem. It is planted in a loamy free-
draining soil. I have used about a cup of cotton-
seed meal to fertilize each spring. Any idea of
what the problem might be? Thank you!

The brown spots are most likely the result of fungal infection. Rhododendrons are subject to a great many of these, but most are are more of an aetsthetic problem rather than a threat to the plant's continued health. Using a fungicide, either systemic soil drench or a spray, can halt its spread protect newly emerging leaves.

The unhealthy yellowish color indicates a nutritional problem. The place to begin is a soil test, including the soil's pH.
