Setup, Compatibility & Care
Soil Preparation: Ensure your planting site or container has excellent drainage. If your soil is heavy or prone to waterlogging, add grit or horticultural sand to improve conditions.
Planting Depth: Position bulbs at a depth roughly twice their own height to protect them from frost while allowing for strong root development.
Sunlight: Choose a site that receives full sun to encourage blooming and prevent the foliage from becoming stretched.
Post-Flowering Care: After the blooms have faded, it is vital to leave the foliage intact. Allow the leaves to wither and die back naturally; this process channels energy back into the bulb to sustain growth for the following year.
Container Care: If grown in pots, ensure they are raised slightly off the ground on 'pot feet' to prevent water from pooling at the base.
