My new Gibraltar Azalea (planted early fall 2007) did amazingly well following what was a good old fashioned (heavy snow) winter in PEI. Around mid-June I was delighted to see new healthy growth and lots of blossom beginning. Then several weeks ago, everything stopped it seemed. The blossoms remained closed as I impatiently awaited what I imagined would be a spectacular full bloom. Having never grown azalea's, I did not know if this was normal (to wait so long). Then I noticed about 10 days ago everything began to wilt and the unopened blooms were falling. Coincidentally (or not) around that same time my husband spread a dark pine (?) mulch over the beds - including around the base of the azalea. Is it possible something in the mulch affected it? Other conditions seemed ideal (sun, water etc.).
