my azalea looks dead
"If damage has occurred from poor drainage over winter, there's little that you can do to correct what damage has already been done. However, as you note, it is still early spring, and the plant may yet leaf out. Shrubs often leaf out a bit late the year after being planted.
If your azalea is still alive and healthy, consider planting it in a raised mound of soil to which you've added plenty of acidic peat moss. This will get the root zone up out of wet conditions and acidify the soil."
