Low growing Azaleas are used as foreground plantings.

Azaleas Planting

The Azalea Plant will perform best in locations that have filtered light. Partial shade under trees give the best conditions for healthiest growing azaleas, and highest flowering. Extreme dense shade will reduce plant growth and flowering. Azaleas exposed to direct sun in the morning after a freeze are extremely susceptible to cold injury. Frozen twigs and branches that rapidly thaw can result in ” Bark Splitting “. Branches with split bark usually die weeks or months after injury.

Azalea plants should be planted in well – drained soil. Organic soils with a P H level of ( 4.5 to 5.5 ) is best suited for Azaleas. Organic peat can be added to the back soil when planting, but rate should not be exceeded 1/3 by volume. Organic mulch can be placed around the plant at a depth of 2 – 3 inches. Do Not pile mulch up against the trunk, stems and branches.

The planting hole for Azaleas needs to be wider than the ” root ball”, leaving space for the roots to grow laterally. Do Not compact dirt around the “root ball” in the hole when filling it back with soil. The Azalea plant should be planted level or slightly above the top of the hole. Azalea plants need to be spaced apart according to their mature size when established ( generally 3 to 5 ft. apart ), when being planted.

Water as soon as possible after planting and twice a week for the first month, depending on rainfall. Established Azalea plants need to be watered every 10 days to 2 weeks, depending on rainfall.

Pruning Azaleas

Pruning the Azalea plant is needed for it to grow full and to be well- branched. Proper pruning is important for Azaleas to remain healthy, grow shapely, and for good flowering. Hard pruning such as shearing or ” cutting back ” with a chainsaw is not recommended. Only light pruning should be done on Azaleas. Light pruning is done by removing any unwanted branches, all dead branches, and to shape up the plant.

Established Azaleas should be pruned after the flowering season has ended, and  flowers are completely gone. Light pruning is done early in the active growing season for Azaleas to grow compact, and to produce numerous branches. Do Not prune Azaleas at the end of winter. If pruning is done after bud development has been initiated, the number of flowers will be reduced. Plus vegetative growth stops after bud initiation has begun.

Fertilizing The Azalea Plant

The Azalea Plant is considered to be acid loving. Azaleas need an Acid – Formulated ” Complete ” granular fertilizer to grow healthy. It is recommended to use a” Slow – Release ” Fertilizer. Brand name products that are sufficient can be purchased at garden centers. Usually the product should list Azaleas on it. Follow directions on the label for amount needed to be applied.

Light granular applications should be done in spring, mid – summer, and in the fall. In the lower southern states it can also be done in the winter. In Florida it is recommended that an application be done in the winter also. Water after applying granular fertilizer so roots can absorb the nutrients.

Micro nutrients are also needed on a routine basis between seasonal applications, for the Azalea plant to stay healthy year round. A good way to do this is by spraying the plant with Liquid Azalea Food. There are brand name products available at garden centers that can be attached to a hose, and the  proper amount needed is sprayed making it easy. Follow directions on the label.

Azaleas are known for their beautiful colorful flowers in the spring time. Year round they can make an excellent shrub with evergreen foliage. The Azalea plant has been a big part of landscapes for many years, and will remain as one of the most widely used shrub. They are a great addition to any home.
