Care Guide

Watering

Keep soil moderately moist during active growth periods

Fertilization

No regular fertilization required; low-fertility soil supports healthy growth. Avoid high-nitrogen fertilizers to prevent excessive foliage growth over flowering

Crushed eggshell powder:Sprinkle a thin layer of finely crushed dried eggshells on soil surface to add calcium without overfertilizing the low-fertility preferred growing medium
Pruning
  • Deadhead spent blooms to extend the flowering period by 1–2 weeks
  • Remove faded, yellowing foliage after the plant dies back in late summer
  • Thin overcrowded clumps during early growth to improve airflow and reduce disease risk
