When planting container-grown plants, disturb the roots to break the circular pattern. It may be necessary to make vertical cuts into the root ball to break the circular pattern. Do not plant any deeper than the plant was originally planted in the container. Planting azaleas deeper than the original planted depth assures disastrous results. Apply 2 to 4 inches of pine straw, pine bark, or other suitable mulch material after planting.
Azaleas have an extremely fibrous root system that remains relatively shallow.
A good watering schedule is essential during the growing season. Azaleas need the equivalent of 1 inch of rain every 7 to 10 days. Be sure to continue watering during late summer and until winter rains begin. Azaleas have shallow roots and can easily be damaged by cultivation such as hoeing or raking. Azaleas can be pruned in early spring immediately after flowering.
