I have a couple of 'Elsie Lee' azaleas purchased last year that have been healthy until recently when I noticed what looks to me to be fertilizer burn. Both plants are covered with buds (just ready to open) that look like they might be affected somewhat? hard to tell-anyway, if this is the case with the burn, will these buds still open and flower? Also, is there anything I can do to alleviate the problem? Thanks!!!
