Rhododendron x
Bloom-A-Thon Azaleas are prized for their show-stopping blooms that last longer than old-fashioned varieties. As a bonus, they’re able to rebloom again in fall and bear foliage through winter. Bloom-A-Thon Azaleas are perfect for mass plantings, mixed borders, containers, or as a specimen plant.
As with all azaleas and rhododendrons, Bloom-A-Thon Azaleas need acidic soil to thrive. Use ammonium fertilizers regularly to maintain a lower soil pH.
Featured Varieties:
Bloom-A-Thon Double Pink – Double pink flowers. 3-5 ft tall by 3-4 ft wide.
Bloom-A-Thon Red – Red flowers. 4-5 ft tall by 3-4 ft wide.
Bloom-A-Thon White – Crisp white blooms with heavily ruffled edges. 3-5 ft tall by 3-4 ft wide.
Bloom-A-Thon Lavender – Bright, deep lavender flowers. 3-5 ft tall by 3-4 ft wide.
- Azaleas need shade through Missouri’s hot summers, but they bloom best with at least 4 hours of morning sun.
- Avoid planting in soggy or poorly-draining sites, as Azaleas are prone to overwatering. However, they also don’t like to dry out completely! Mixing compost into the soil at planting time and using a wood mulch will help maintain even soil moisture.
- Azaleas strongly prefer acidic soils. Regular use of a soil acidifier such as Aluminum Sulfate or an azalea-specific fertilizer will help achieve the lower pH, but it will dissipate over time. Growing healthy azaleas requires more care than most shrubs for this reason!
- Azaleas don’t typically require pruning. If needed, they can be trimmed after the spring bloom, but before July.
