Bloom-a-Thon® Red Rhododendron Shrub

Bloom-a-Thon® Red Rhododendron Plants offers full, rich, coral-colored blossoms that rebloom all season long. Even the hot weather doesn’t stop this plant from showing loads of late summer and fall flowers. Flowering lasts for 4-6 weeks in spring, and then another 12-16 weeks in summer and fall.

Planting Instructions:

• - Can be planted anytime the soil temps are 60F

Soil Preparation:

• - Ideal soil pH: 4.5-6.0, requiring acidic conditions
• - Prefers well-drained, loose, and organic-rich soil; avoid heavy clay or overly wet conditions

Watering Specifics:

• - Water deeply and regularly during the first growing season to establish roots
• - Keep soil evenly moist but not soggy; Rhododendrons do not tolerate drought well

Fertilizer Type:

• - Use a fertilizer designed for acid-loving plants, applied in early spring
• - Avoid over-fertilizing, as Rhododendrons are sensitive to excess nutrients

Pruning and Training:

• - Prune immediately after flowering to shape the plant and encourage new growth
• - Remove any dead, damaged, or crossing branches to maintain healthy growth

Additional Pest Management:

• - Monitor for common pests such as lace bugs, weevils, and spider mites
• - Ensure good air circulation to prevent fungal diseases like powdery mildew or root rot

Temperature Tolerance:

• - Tolerates heat and cold once established
