Did you fertilize it recently? The are easily burned by fertilizer and this is known to cause sudden leaf drop in the plants.

Azeala Leaf & Plant Problem

(1) I live in Florence, NW Alabama. I have 14 Encore Azaleas, 11 are blooming very well, even in November. Three are stunted and their leaves are small, darker green in color mixed with a brown or purple tinge. They have produced a few flowers, but much smaller than the other bushes. Can you tell me what is the problem please?
(2) I understand that the best time to prune these plants is after the first flowering in the Spring. Is this information correct?

1) It sounds like it may possibly be root rot. Here it an article on the root rot: http://www.gardeningknowhow.com/ornamental/shrubs/azalea/phytophthora-root-rot-azaleas.htm Unfortunately, we would recommend pulling the affected plants out ASAP.

2) Yes, this is correct. This article will help you with that: http://www.gardeningknowhow.com/ornamental/shrubs/azalea/pruning-azaleas.htm

Azalea Disease on Leaves

I have a number of Azalea plants in pots that I’ve had for about 11 years. I keep them under shade cloth in the summer in an easterly direction and in the winter I put them in a round garden on my front lawn. They love it there and they always flower beautifully. I live in the central wheatbelt of Western Australia and our summers are very hot and winters are cold and frosty. This does not seem to worry them at all, but this year they have what appears to be a white to grey appearance on the outside of the leaf and on the under side little black spotted things. Please can you help, as I said the summer doesn’t worry them as long as they are under the shade cloth, and of course, kept watered and the cold frosty mornings when we have them in winter doesn’t bother them.

The problem could be attributed to the azalea lace bug. Here is an article that you may find helpful: http://www.gardeningknowhow.com/ornamental/shrubs/azalea/azalea-lace-bug.htm

Azaleas With Yellow Leaves

I planted 13 azaleas in my front yard about 5 months ago and now the leaves are turning yellow. Why?

It sounds like either a nutrient deficiency or a drainage problem. Have your soil tested, then amend the soil accordingly and make sure that the plants are not in standing water

Azalea Spotting

I planted 5 gallon-sized azaleas last spring. Now they have yellow leaves with some brown spotting and they’re easily pulled off the plants. How can I cure this problem?

It sounds like a fungus, likely Leaf Spot Fungus. This article will help you:

Any Ideas as to Azalea Losses?

I am on Wadmalaw Island SC. I have about 30 well established large azaleas and about 20 small “suzikis” (sp) About two years ago some of both varieties started getting yellow leaves and then dying branch by branch. I saw no obvious pests, and cut out the branches. The bush died anyway. The problem has slowly spread bush by bush from the first area. Any suggestions?

Unfortunately, I suspect that it may be Phytophthora Root Rot. This article will have more information:

I like neem oil myself. You have to buy it, but it is organic, safe for people, pets and good bugs and very effective. Here is more information:
