Optional diluted organic feed once monthly if soil is very low in nutrients. Do not use high-nitrogen fertilizers, as they can disrupt natural growth habit
Eggshell powder top-dressing：Crush dried, rinsed eggshells into a fine powder; sprinkle lightly on the soil surface to boost calcium levels without overfertilizingPruning
- Deadhead spent flower heads to prevent unwanted self-seeding if desired
