|I have about 50 plants in the same growing conditions, about 4-6 hrs of sunlight daily. The are all the same large purple flower varity. Some are loaded with blooms some have no blooms. I mean these plants are literally next to one another yet some have no blooms at all. Can you advise what my be wrong? Thanks, John.|
|If all plants are enjoying the same health the only reasons for non-blooming are flower bud damage from late frost or pruning at the wrong time. Azaleas develop flower buds during the summer months and they just sit quietly and wait until warm spring weather. Because they are exposed, sometimes winter weather will kill them off. And, sometimes we accidentally prune them off. The only other possibility is that your non-flowering azaleas might need a dose of fertilizer. Use a 5-10-10 or 10-20-20 to encourage flower production.
Good luck with your azaleas.
