Hi! I was wondering if somebody on this site would be able to help me with my azalea.I live in Maryland, towards the western side. We've had a cool wet spring. I have two azaleas in the front of my house, one is existing from when we moved in and one I planted next to the current azelea. The azelea in question has always done amazing, for some reason it grows so much quicker than the the one I planted next to him. He started out with lots of new growth, but not many blooms this year. I sprayed him early with a rose generic fungicide to hopefully ward off any of the diseases that they seem to be prone to.it was about two weeks ago that I sprayed him. I don't remember the weather but I know better than to spray an oil in the heat of the day. So I can't imagine this is leaf burn but I guess you never know. The black leaves are heavier in the back of the bush which is extremely dense and thick, but it does cover the whole azalea. You cannot scrape the black off, it is not a mold, and the underside of the leaf has no black spotting on it at all. No pests are present at this time.

Azaleas need some sun, good air movement and a bit of fertilizer. The buds for this year's bloom were set down last summer. So this year's wet spring is not the cause.
I had seven azaleas years ago on Long Island that some one gave me. They were being shaded out at his house. They were sickly plants but with three years of proper watering, a good four hours of sun per day, and three to four feedings of Mir-acid each spring and summer, they drastically improved!!! They became gorgeous!!!
