Propogation by division

From Late Summer TO Early Autumn

After dead heading and when foliage has died, lift the bulbs. Remove the soil from the bulbs and remove any offsets that appear damaged or diseased. Separate the remaining bulbs and when they are dry, store in a dark well ventilated space. Bulbs can then be replanted in late Autumn.

 

Planting

From Early Spring TO Early Spring

Albuca bulbs require sandy, loose soil which drains really well. Place them in full to partial sun to produce their spectacular blooms. They are not frost hardy thus if planted outdoors in areas prone to frost, they will need to be brought in over winter as cold temperatures can damage the bulb. If planting in the greenhouse, use a suffice cactus soil with some peat (a soil that retains water yet drains well).
