Help! I have 4 Hino Crimson azaleas that did not bloom or even bud this year! They have bloomed consistently in past years. I did not prune them last year so it cannot be due to pruning. 1 is an old and large azalea the other 3 are newer (3 or 4 years old). I can't figure this out and have not found anything online. Some of the leaves are a little reddish now ~ not sure if that has anything to do with it. Any words of wisdom would be greatly appreciated!
