Care Guide
Watering
Keep soil evenly moist during active growth; reduce watering only if plants show wilting during dry spells
Fertilization
Optional diluted compost tea application once to support early growth. Over-fertilization may reduce flowering and promote leggy growth
Composted eggshell powder：Sprinkle a thin layer on soil surface in early spring; avoid direct contact with plant stems to prevent burningPruning
- Deadhead spent flower racemes to encourage extended blooming through the growing season
- Trim back overgrown stems to maintain a compact, tidy form
- Remove dead or yellowing foliage promptly to reduce mold growth risk
