Care Guide

Watering

Water when the top 2–3 cm of soil is dry; reduce watering during periods of heavy rainfall

Fertilization

Apply a diluted balanced organic fertilizer once monthly. Over-fertilization can reduce fragrance and compact growth habit.

Eggshell powder top dressing:Crush dried eggshells into fine powder and sprinkle a thin layer around the base of plants; avoid direct contact with stems to prevent fungal growth.
Pruning
  • Trim back spent flower heads immediately after blooming to encourage prolonged flowering and maintain compact growth.
  • Shear lightly in early spring to remove dead foliage and promote fresh new growth.
  • Thin overcrowded patches to improve airflow and prevent fungal disease.
