Hi Jan,
I didn't know that Pieris 'Forest Flame' is supposed to have eracacious compost, feed or mulch???!!! I have 5, ranging from young baby size to reasonably sized, and lots of white bell flowers and red tipped leaves. I've always just stuck them in multipurpose compost. One of mine is in semi shade, and the others in full sun. Either way, they're all doing as they're supposed too. I'm just as confused as you now. Hope someone can set us both straight
