ð§ How to Water
Water well right after planting. From autumn to spring, water about once a week if there is no rain and the soil is dry 3 cm down. Once the leaves yellow in late spring, stop watering: dormant corms rot in damp summer soil.
âïļ Lighting
Full sun, 6 or more hours a day, so the flowers open fully; in shade the stems flop and the flowers stay closed. Light shade under deciduous trees works well.
ðŠī Ideal Soil
Light, well-drained soil of average fertility with a near-neutral pH. In clay, mix in coarse grit; in containers, use bulb compost with a third of sand or perlite.
