Soil Requirements
Purple azaleas prefer acidic, well-drained soils. Incorporating organic matter can enhance soil quality and promote healthy root development. Regularly testing soil pH can ensure optimal growth conditions.

Purple azaleas require consistent moisture, especially during dry periods. However, avoid overwatering as this can lead to root rot. A layer of mulch can help retain soil moisture and regulate temperature.

To keep your azaleas vibrant, use a fertilizer specifically formulated for azaleas and rhododendrons. Apply in early spring as new growth appears, and follow up with another application after blooming.
