Crinum lilies are large, heat and moisture loving plants, producing an abundant array of showy flowers in summer.
Lilly like their soil rich, but exceptionally well-drained, so ideally create a mix from one part well-rotted manure, one part horticultural grit or sand, and two parts leaf mould. Two-thirds good compost mixed with one-third grit also does fine.
Crinum Planting Procedure:
Each bulb needs to be planted right side up
The more pointed end is considered the top
Plant each bulb in a hole that is just deep enough that its neck is protruding from the soil and the bottom of the bulb is covered in soil
Covering the entire bulb with soil and planting too deep discourages flowering
Space bulbs at least 8 inches apart and water the planting site or container well after planting
Plant the bulb, or place the potted bulb in a warm place with direct light since heat is necessary for the development of the stems.
