I have three coral bell azaleas that I planted about three or four years ago in a planter box on my deck. The first two years they bloomed but the last two springs they have formed buds that have never bloomed. They seem to dry up after the first ring of leaves around the bud turn brown and dry. Last year I thought they might have frozen with a late frost and I suppose that might have happened this year except the brown leaves appeared before we had the late freeze. TIA Laurie

I got a lot of good information here. I am planning on planting 30 in raised beds...wish me luck!
