1. Trimming Azaleas

Asked by Anonymous - October 24, 2011

It’s late fall. Is it too late to trim my azalea bushes?


2. Burning Bushes and Azaleas

Asked by Anonymous - October 25, 2011

I have two larger 5′ tall burning bushes that I want to transplant. Can I cut them back low and then transplant and are there any special concerns for that? I also have azaleas that are not doing well. They are sparse and small. I want to move them into the sun again transplanting and cutting back. Please advise.


3. Why Are My Azalea Bushes Red

Asked by Anonymous - October 25, 2011

My azalea bushes have turned a ‘reddish’ color in the past few days. I have never seen this happen in the fall any other year. I’m afraid they are diseased. Can you advise me if the bushes are infected? And if so, can they be saved, or must I remove them?


4. Diseases Affecting Azaleas

Asked by yarwood1 - November 19, 2011

We have recently transplanted an azalea from another garden. It now has a sage green coloured fungus which is situated between the forks of the branches. Need to know if this is fatal or whether it can be treated, and if so, how?


5. Blue Spot on Azaleas

Asked by highroller2 - February 14, 2012

Something is causing almost all of the foliage (leaves) to drop off the branches as if my azaleas are dying. I think I can see what I have been told is BLUE SPOT. What can I use to save my azaleas?

  • It sounds like it may be Cercospora Leaf Spot. It causes blue spots in some varieties of azalea (and red in others). The defoliation is unsightly, but will not kill the plant. To treat it, just spray the plant with a fungicide. You may want to repeat the treatment every few weeks until you are sure it is cleared up.

6. My Azaleas Have a Brown to White Color on the Leaves

Asked by mmcave777 - March 14, 2012

Leaves brown and white, looks like mildew, but it’s not affecting the new growth. Also, doesn’t bloom as much as it should.

7. Remove or Treat Sick Azaleas

Asked by turtle2 - March 17, 2012

My azaleas have new growth only at the ends of the stems. The stems, other than at the ends are bare. I had very few flowers this year and the plants look dreadful. How can I get the plants to fill out and become healthy for next year? Are these symptoms of near death experience requiring removal and replacement of the plants? Thanks, Bob

  • I would check the roots. Leaf loss on older parts of the plant are signs of Phytophthora root rot, which is not curable and the plants would need to be removed. But, it could be just run of the mill fungus as well.

    Check the roots. If you see signs of root rot, the plants need to come out. If you do not see signs of root rot, treat with a fungicide and see if that does not clear things up a bit.
