For spectacular color, add azaleas to your outdoor landscape. One of the main causes of death for azaleas is improper planting, so follow these tips for better results.
• Locate plants on a shaded location in the north, east or northwest side of a building – and a location sheltered from winter sun and winds.
• Thoroughly work the soil bed, and add peat moss and compost.
• Set the plant slightly higher than ground level, keeping 1/3 of the plant above ground. This prevents it from sitting in too much water.
