Keep soil evenly moist but not waterlogged; reduce watering during prolonged dry spells only if wilting occurs
Apply diluted balanced fertilizer once at planting. Do not over-fertilize, as it can reduce alkaloid content and weaken overall plant health
Crushed eggshell powder：Mix dried, crushed eggshells into the top 2 cm of soil to boost calcium levels and improve drainage; avoid raw egg products to prevent pest infestations- Remove spent flower heads to prevent unwanted self-seeding in managed gardens
