Care Guide

Watering

Water sparingly during active growth; allow soil to dry completely between waterings

Fertilization

No regular fertilization required. High-nutrient soil may cause leggy growth and reduced drought tolerance

Crushed eggshell topdressing:Sprinkle a thin layer of finely crushed eggshells around the base to enhance soil structure; avoid overapplication to prevent nutrient buildup
Pruning
  • Trim back dead foliage and spent inflorescences after flowering to tidy the planting area
  • Remove self-seeded seedlings if spread outside desired growing areas
  • Avoid heavy pruning, as delicate stems may break easily
