Care Guide
Water moderately during active spring growth; reduce watering in summer to prevent root rot.
Apply a light, balanced organic fertilizer or compost top-dressing in early spring before new growth begins.. Requires very little feeding; over-fertilization leads to excessive foliage at the expense of flowers.
Crushed Eggshell Powder：Wash, dry, and finely crush eggshells. Sprinkle around the base of the plant to provide slow-release calcium, which perfectly supports its preference for alkaline soil conditions. Avoid using high-nitrogen kitchen scraps.- Shear the plant back by half immediately after flowering finishes in early summer;
- This prevents the center from dying out and becoming woody;
- Encourages a tight, compact, mat-forming habit for the following year;
- Remove any dead or damaged foliage in early spring.
