Water: Water sharp blazing star sparingly when bulbs sprout to prevent soil-borne diseases. Increase moisture as growth progresses, keeping soil slightly moist. In winter, reduce watering to avoid soggy soils that can harbor diseases during the overwintering period.

Fertilize: Sharp blazing star typically doesn't require fertilizer if grown in healthy soil. However, adding an all-purpose or slow-release fertilizer can benefit initial growth in spring, especially if growth is slow. In rich soils, additional fertilizer is rarely necessary.

Pruning: Sharp blazing star features tall spikes of purple flowers and benefits from early spring pruning. Trim old flower spikes and remove damaged stems to promote new growth and blooming. Regular pruning enhances health and appearance. Always use clean, sharp tools to prevent infections.

Propagation: Sharp blazing star is best propagated by division in spring, when foliage emerges. Cut back leaves to 10-15 cm to ease removal. Ensure each new bulb has at least one eye, minimizing root damage. While possible, growing from seed is slower and less efficient.
