Watering, pruning, propagation, and repotting details from plant data
Keep soil consistently moist but not waterlogged. Water deeply when the top few centimeters of soil feel dry. Reduce watering in winter when the plant is dormant.
Ensure good drainage to prevent root rot, especially in containers.
Remove dead or damaged foliage in late autumn or early spring. Cut back flowering stalks after blooming if you wish to prevent seed formation and encourage plant vigor. Harvest edible stalks by cutting them at the base.
Propagate by dividing established clumps in early spring before new growth begins. Sow fresh seeds in autumn or early spring in well-drained soil. Allow seeds to stratify naturally outdoors if sown in autumn.
Repot container-grown plants every 2-3 years in early spring. Choose a pot that is at least 30 cm in diameter and depth. Use a well-draining potting mix, and ensure the crown of the plant is just at the soil surface.
