(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: https://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: https://www.gardeningknowhow.com/ornamental/shrubs/azalea/pruning-azaleas.htm
I have heard about the Encore azalaes and would like to know more about it. How long do they stay in bloom and how much maintenance do they require?
The bloom times of azaleas varies quite a bit, depending on the variety and on the weather. Most bloom in April and May, and most of the blooms appear all at once and last about two weeks.
My 10 year Encore Azaleas are completely bare. First time ever. Also, first year I have used a lawn and shrub service to fertilize my shrubs. They also sprayed insecticide on them. Service began in May and now I discovered my Encores, which have been gorgeous, are now sticks. I have never had any issue before and my azaleas have been beautiful and occupy a large area around the back side of my house. It will be costly to replace, especially since they have 10 years of growth.
I don't know what could have happened to your azaleas, but something apparently has. I would start by discussing this with the landscape co. Also, take some samples of soil, roots, branches, and any dead leaves if you can find them, to the County Extension Service for analysis.

If the landscape service is responsible, they should be glad to make right any damage they did. If you feel they are responsible and they won't admit to it, you should consult with a lawyer.

I'm sorry your Azaleas are suffering! If the only thing that's changed is the service you used to fertilize them, it would seem that's the culprit, but this article also gives you a couple of things to check to see if you have a pest problem, a type of leaf fungus or root rot: https://www.gardeningknowhow.com/ornamental/shrubs/azalea/no-leaves-on-azalea.htm
Last spring planted four encore azaleas and they grew and thrived through winter here in Anniston Alalbama. about thtree weeks ago they were loaded with beautiful flowers. went on the web for spring hints. had put bark down when planting so put a 1/4 tsp of azalea fertilizer at base. watered at base and lightly sprayed with spectroside disease and bug spray. to my chagrin all the flowers fell off. please tell me what i did wrong and what to now do margot joyce
Flower drop could be due to the natural aging of the flowers. Encore will bloom early spring, then set buds again, and then bloom once again in the fall.
A drought or roots that are dried out can also cause the flowers to drop.
Check the moisture level in the soil.
A balanced granular fertilizer is recommend. Check the numbers on the fertilizer that you used. The numbers should all be the same.
Make sure the spectraside you used specifically says you can use on Azaleas. Is there a reason you sprayed your plants?
Unless you specifically have a pest issue, applications of a chemical spectracide is not needed.

The stems of my encore azaleas have turned black and appear to be spreading to the leaves and possibly to nearby plants & shrubs. Should I spray with Malathyon or something else? Should I prune back some branches?
This sounds like Azalea Bark Scale.
