Care Guide

Watering

Keep soil slightly moist during germination; reduce watering once plants reach 10 cm tall

Fertilization

Light top-dressing with compost at planting. Avoid high-nitrogen feeds to prevent excessive foliage growth at the expense of seed production

Composted eggshell powder:Sprinkle a thin layer around base at planting to improve soil structure and nutrient availability
Pruning
  • Trim senescent foliage after flowering to prevent unwanted self-seeding in managed areas
  • Remove competing weed grasses to reduce resource competition during seedling growth
  • Cut back entire plant to ground level after seed harvest for seasonal cleanup
