Purple Formosa Azalea Care
Hardy from USDA Zones 7-10.
Plant in Partial Sun for best results. Filtered Sun for much of the day or 2-3 hours of direct sun a day is sufficient. Too much sun will stress the plant, while too little sun will result in decreased foliage and bloom potential.
This rhododendron has only medium water requirements once established. For the first growing season, provide supplementary water 2-3 times a week in average weather conditions.
The Purple Formosa Azalea prefers acidic to neutral soil for the best results. In addition, ensure that the soil drains well in order to avoid root rot.
Fertilize in early spring with balanced acidic plant fertilizer. This will help ensure future growth and blooms, as well as promote the overall well-being of your plant.
Trim after the bloom cycle has ended. The Purple Formosa Azalea, like other yearly blooming rhododendrons, begins compiling the next years’ blooms after the end of the current year’s cycle. Trimming too late will decrease the number of potential blooms for the next year.
