Vegetative Growth
Spring through early summerPlant develops dense foliage and branching structure; leaves are glossy green
Water regularly. Apply balanced, acid-forming fertilizer (rhododendron formula) monthly during growing season. Pinch back new growth if needed for bushier form.
First Flowering

Fun Facts
- 🌱 The 'Bloom-A-Thon' series was developed through extensive breeding by the University of Georgia specifically to produce azaleas that rebloom multiple times throughout a single growing season, breaking the traditional single-bloom pattern.
- 🌱 Unlike many azalea varieties that bloom once in spring, Bloom-A-Thon Pink can produce 3-5 distinct flowering cycles from June through fall if deadheaded consistently.
- 🌱 Azaleas and rhododendrons are in the same genus (Rhododendron), with azaleas generally being deciduous and smaller-leaved, while rhododendrons are typically evergreen with larger leaves.
