(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? -

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