I have spent somewhere between 400 to 600 dollars just on plants. I have dug out two beds (one raised) and replaced 2/3 of the dirt with peat moss, washed sand and compost, and mixed in various sulphur conditioners to acidify the soil. Some of these contained iron, manganese or zinc, and yet I cannot get an azalea to live for more than six weeks. I break up the rootball before planting, and soak the soil halfway through the fill process and afterward. I even use acidized water for watering. I do all these things because my soil is extremely alkaline. What else can I do?
