Encore Hybrid Azaleas

All Azaleas fall into the Rhododendron family!
These are the recent hybrids of Azaleas that offer showy flowers during both spring and fall.
Azalea bushes thrive under the partial, filtered shade of pine, hickory and Oak, along with companion dogwood trees and camellia shrubs. Azalea plants prefer grown in partial shade ( 4 to 6 hours of sun but not during mid day ), and when planted next to buildings, the north side offers protection from cold damage. The flowers of the azalea plant last longer in filtered pine tree shade because of the cooling effect. Pine tree straw, pine cones, and pine tree bark make excellent mulch under azaleas because it both cools and acidifies the soil. When planting azalea bushes, the shrub should be put into a landscaped hole containing 1/2 soil & 1/2 organic matter, such as peat moss, leaf gro or pine bark. Azalea plants are very shallow rooted and do not do well in compacted or heavy clay soils.

Azaleas love acidic soils, and a pH of 4.5 to 5.5 is perfect for vigorous growth. Watering may be essential if significant rainfall does not occur over two week period and fertilizing is usually not recommended. Fertilizer can burn the tender fibrous roots and may even kill the plant. If yellowing occurs in the leaves or leaf veins, Iron or Magnesium (Epsom salts) can correct the situation. NEVER put lime on an Azalea plant, not only is it wasting money, it can kill the plant.
Healthy Azaleas have bright green glossy leaves in the summer. If the leaves are dull green above and reddening below, that may signal phosphorous deficiency. It is ok to put a water soluble phosphorous fertilizer on the plant but AVOID NITROGEN!
Pruning should be done immediately after blooming to ensure good bloom the following season.
Azalea shrubs are propagated easily by taking a cutting about 8 inches long and placing the cut end about 2 inches deep in sand. These cuttings may root within a week during June and July, and the plant may grow another foot tall before being ready to be planted permanently.
