Sow seeds on the surface of moist, finely prepared soil and press gently without deep covering. Keep the soil evenly moist until germination. Thin seedlings after emergence to provide sufficient space for mature growth.

Water regularly while seedlings establish, then reduce watering as plants mature. Grow in well-drained soil with full sunlight. Remove spent flower spikes after blooming if desired. Avoid prolonged waterlogging around the root zone.
