Thinning rhododendrons
I live in southern Oregon. I moved into this home 2 years ago. The flowers in the yard have been in place for over 20 years. I have seen pictures of the rhododendrons before we moved in and they were full and beautiful. The first year the plants were "ok" many blooms, but I noticed leaves were starting to fall off. This last year same thing. The plants just aren't as full and healthy looking as they once were. Is there a special fertilizer I should be using? Should I prune them? Thanks! Debbie

Thanks for writing! Rhododendrons typically do well without any special care in your area. It might be that the plants are getting old and lose their vigor; this is not uncommon. (Unfortunately, not every plant is as long lived as a redwood!)

You can also try doing a soil test and seeing what the ground is like --- a soil test will tell you if there are nutrients the ground lacks or has too much of. Many soil tests also tell you what and how much of it to add to improve your soil.

Good luck!
