Rhododendron calendulaceum, the flame azalea, is a species of Rhododendron native to the Appalachian Mountains in the eastern United States. It is a deciduous shrub, 120–450 cm tall. The leaves are 3–7 cm long, dull green above and villous below.
Flame azalea is appropriately named for the clusters of brightly colored, 2-inch blooms that decorate the shrub from late spring to midsummer. The funnel-shaped flowers range in color from yellow to orange and deep red. The foliage often turns red or soft yellow before leaves drop from the plant in late autumn. Flame azalea is a versatile shrub that is stunning in almost any setting. The showy shrub is especially dramatic when several are planted together, but be sure to allow at least 4 to 6 feet between each plant.
Watering azaleas successfully is all about creating soil that is moist in the growing season and adjusting the conditions to promote moisture retention in conjunction (such as added mulch) with additional watering to maintain the correct balance. it is important to prepare the soil beforehand with water retaining materials such as leaf mould.
Liquid fertilizers are applied more frequently, bi-weekly or monthly, for example. Granular products are used less frequently, perhaps once every month or two. Slow-release houseplant fertilizers break down slowly and release their nutrients in small amounts, over a longer period of time. A single application of most of these products lasts for three to four months.
The plant is hardy to areas with the lowest winter temperatures of -26.1°C (-15°F). The plant doesn`t like hot summer weather.
Whether it be plastic or clay, make sure the pot you select has drainage holes in the bottom to prevent over-watering.
