Formosa Azaleas are evergreen shrubs known for their showy, lustrous pink flowers and growing formosa azaleas is not difficult. They are quite the visual treat with abundant blooms and are great additions to any garden. Generally they are maintained to heights of about 4 feet, though they can grow as high as 8 feet tall. The best part about these shrubs is that they are really easy to grow and care for and can provide year-round beauty.
These shrubs grow well in areas of shade to partial sun. They actually grow really well when planted beside larger trees as trees provide adequate shade and block direct sunlight. The formosa azalea is popular in the South because it provides the ideal growing climate. They do not grow well in colder areas and can only survive temperatures as low as 10-20º F. Also, make sure the soil you plant your azalea in is rich and well drained. If needed add compost to aid in drainage. When planting, dig a hole that is roughly as deep as the container your azalea came in and slightly wider. Make sure not to plant the shrub below the soil surface, as this will cause your azalea to drown and die prematurely. When planted, apply a 3-inch layer of mulch around your plant ring. Make sure not to mulch at least 10 inches around the trunk of your plant. All planting should be done in early spring.
The most important time to water is during the shrub’s first growing season. This is when its root system will develop so make sure to follow a regular watering schedule. Water once a week during the first few months of growth and gradually decrease your supply until your shrub matures.
After its first growing season, you can begin to prune your formosa azalea. Feel free to shape your shrub as desired and trim back early on to maintain a shorter height. All pruning should be done in late summer after the first bloom as this will allow enough time for re-budding and future blooms the following spring.
