Native Azaleas are definitely a spectacular show in spring, but don’t wait till Spring to plant them! Shrubs planted in Fall have a much better chance to get established and become healthy plants by next summer.
The American Native Azaleas, species Rhododendrons, are deciduous, meaning they lose their leaves for the winter. This defoliation begins quite early in fall, depending on the climate conditions and the variety. Usually the earlier the bloom time in spring, the earlier leaf loss occurs in Fall.
Fall is the best time to transplant shrubs because they are then dormant. Fall planted shrubs have all winter to become established before time to bloom and grow next year. This is especially important when your plants are received by mail, as is most often true with rare plants like native azaleas.
When planting native azaleas, soil preparation is key. All azaleas prefer well-drained soil. Amend the soil for drainage, especially if your soil is clay. Prior to planting your native azalea, work in some compost or composted manure and shredded bark to the planting hole. To help insure good drainage, mound up the soil so your azalea is planted high. Be sure that the root collar is slightly higher than soil level so water will drain away when those heavy downpours occur.
When planning your native azalea garden, consider the site. Native azaleas naturally occur in the filtered light beneath large trees near stream banks, but will grow in full sun when water is adequate. They perhaps will bloom more profusely in full sun, but need more water with more sun.
Make sure you can get water to the plant if drought occurs. Native azaleas are quite drought tolerant once established, however, water weekly the first year or two, as the plant grows in to its new environment. Also, the blooms buds are formed during late summer on the early blooming varieties, and if your area is prone to a late summer-early fall drought, pay attention to those weekly waterings, so you won’t miss out on your fragrant spring blooms!
Finally, obtain some good organic mulch. Azaleas have a shallow root system. Apply a thick layer of any organic mulch such as shredded bark, leaves, or straw to conserve moisture and keep the roots cool. Never cultivate around your native azaleas, since this can damage those shallow roots.
Once planted, your native azaleas will need water at least once weekly to insure good root development and beautiful blooms for years to come.
