water
Keep the growing medium consistently moist during active growth and flowering. If forcing in water and pebbles, maintain water level just below the bulb base; change water every 3–4 days to prevent bacterial growth and odors.
soil
Can be grown in traditional peat-based potting soil, or forced in pebbles and water (a soilless method). When using soil, ensure excellent drainage. Water-forcing requires only pebbles or gravel and water, no soil needed.
