We recently bought a new home, and as would be expected, the landscaping left much to be desired. They basically dug holes, dropped the plants halfway in them and took off, and our one azalea plant spent a few months poorly planted in hard clay soil in full sun. There were no blooms and all the leaves were a greenish brown, and then last month I dug it up and planted it in good quality soil for azaleas, a wide area of acidic soil with organic matter. Lots of new green growth appeared around the bottom, but the brownish leaves are hanging on and not improving. Now I hear it should have been pruned already. Would I be better off to just leave it alone till next year, or go ahead and trim it down to get rid of the poor growth?
