The Q&A Archives: Care for rhododendron

Question: I have had 2 rhododendrons for about 30 years. They have grown and bloomed very well until last year. They have started to die back and have very little amount of blooming. I have pruned the dead branches off and fed them with Miracle-acid for years. How can I rejuvinate them

Thank you Joe Krohn

Answer: Thirty years is a long time for a rhododendron to grow so your plants are probably in a state of decline because of age. You might be able to coax some new growth by pruning your shrubs back by about one-third. You'll lose next year's flower display but you should get multiple branches and lots of new leaves. This should help rejuvenate your shrubs. Best wishes with your rhodies!
