Sunlight Requires full sun to partial shade; bright direct sunlight promotes abundant flowering, while light shade prevents leaf scorch in extreme heat
💧
Watering Water deeply when the top 5–10 cm of soil is dry; avoid overwatering to prevent root rot, as this species is drought-tolerant once established
🌡️
Temperature Tolerates light frost down to 5°C; performs best in warm, dry summer climates with low humidity

Care Guide

Watering

Keep soil evenly moist during active growth periods, but allow the top layer to dry slightly between waterings

Fertilization

Apply a low-phosphorus, slow-release fertilizer once at the start of the growing season. Over-fertilization can reduce flowering, so use sparingly

Eggshell powder top-dress:Crush thoroughly dried eggshells into a fine powder, sprinkle lightly over the soil surface, and water gently to release calcium into the root zone
Pruning
  • Remove dead, damaged, or diseased branches in late spring after flowering to maintain plant health
  • Thin overcrowded stems to improve airflow and light penetration throughout the shrub
  • Trim back wayward branches to maintain a compact, rounded shape; avoid heavy pruning as it can reduce next year's bloom production
