Overview
These small shrubs were originally used by the Japanese in the art of Bonsai. They have large, unscented funnel shaped flowers in late spring.
Soil: Well-drained soil with high organic matter content is important. Azaleas prefer a soil that is slightly acid and ensure there is a good layer of mulch to maintain moisture levels.
The biggest problems with azalea are due to poor drainage causing the roots to rot or lack of water causing the roots to dry out. Careful selection of the appropriate location and good preparation of the soil before planting will greatly increase the plant's chance of thriving.
Maintenance: It has a shallow root system so keep the roots moist by mulching well with compost and other leaf matter, or grass. Feed with an Azalea or Rhododendron formulation (they have no lime). Trim off spent flower heads and water well in summer
Diseases: Azalea Petal Blight and Azalea Lace Bug are a problem particularly in the warmer areas. There are some hybrids that seem to be more resistant than others, check with your nursery when purchasing plants.
