Care Guide
Watering
Keep soil evenly moist but not waterlogged; avoid wetting foliage to prevent fungal growth
Fertilization
Diluted balanced liquid fertilizer once every 4 weeks. Avoid over-fertilizing, as excess nutrients can reduce the silvery foliage pigmentation
Eggshell powder top dressing：Crush clean, fully dried eggshells into a fine powder; sprinkle lightly on the soil surface to improve soil structure and add calcium without burning rootsPruning
- Deadhead spent yellow flowers to encourage bushier, more compact growth
- Trim leggy stems in mid-summer to maintain the mounded habit
