Care Guide

Watering

Keep soil consistently moist but not waterlogged to support active growth

Fertilization

Diluted balanced liquid feed every 2 weeks. Use diluted feeds only if soil is nutrient-poor; avoid over-fertilization to prevent leggy growth

Eggshell powder topdressing:Crush dried, rinsed eggshells into fine powder; sprinkle lightly on soil surface to add slow-release calcium without burning delicate roots
Pruning
  • Trim back overgrown stems to maintain a compact, even mat form
  • Remove dead or yellowing foliage to improve airflow and reduce disease risk
  • Cut back plants after flowering to encourage self-seeding for next season's growth
