Bright partial sun; avoid harsh midday direct sun which can scorch foliage and damage flower buds
Watering
Water deeply when the top 5 cm of soil is dry; avoid waterlogging to prevent root rot
Temperature
Hardy to -15°C; protect from extreme summer heat above 28°C to prevent bud drop and leaf scorch

Care Guide
Watering

Fertilization
Feed with acidic, rhododendron-specific fertilizer once monthly. Avoid high-nitrogen fertilizers which can burn roots
Composted pine needle tea：Steep fully composted pine needles in water for 24 hours; dilute 1:20 for root drench to maintain acidic soil levels and provide gentle nutrient supplementationPruning
- Remove spent flower heads after blooming to redirect energy to new foliage and bud development
- Thin overcrowded branches in late spring to improve airflow and reduce fungal disease risk
- Trim back stray stems in early summer to maintain the compact mounded growth habit
