Care Guide

Watering

Water sparingly during extended dry periods; avoid overwatering

Fertilization

No fertilization required. Fertilization may encourage excessive foliage growth at the expense of flowering.

Crushed eggshell top-dress:Sprinkle a thin layer of finely crushed eggshells around the base of plants to add calcium and improve soil drainage; avoid thick applications that may trap moisture.
Pruning
  • Remove spent flower heads to prevent unwanted self-seeding in managed garden spaces.
  • Thin overcrowded plants to improve airflow and reduce competition for resources.
  • Pull up entire plants after flowering to control spread in cultivated beds.
