Ledebouria concolor is easy to maintain in cultivation. It should be treated like a succulent plant and be protected from excessive wetness for prolonged periods. Summer watering should be in the form of heavy watering, followed by a long period of drying, approximately once or twice per month. During the dry, winter, dormant phase, the plants should only be watered very lightly once a month. This species is suited to being grown outdoors in warm dry climates that will support it. Bulbs can be used in succulent rockeries and arid gardens, where the plants cannot be overgrown by other vegetation. For best effect, they should be planted in small groups clustered together to maximise the effect of the flowers. They prefer a gravelly, well-drained, sandy soil and can withstand full sun or semi-shade. In wetter climates, they should be maintained under cover, in containers, using a gravel-rich, sandy loam as a growth medium, with small amounts of compost or cattle manure added. Growing the plants in full sun will ensure an attractive and compact growth habit, although they can grow in semi-shade. During the dry, winter, dormancy period, the pots should be moved out of the rain and placed in a dry, cool area with adequate air movement. Watering can commence towards the end of winter at the onset of warmer weather (August–September in South Africa).

Propagation from seed is the best method of producing more plants; the seed must be sown fresh. Sow seeds immediately (do not store them) in spring or summer, in shallow seed trays filled with the sifted potting mixture mentioned above. Sow seed on a firmly tamped surface and lightly cover with the same mixture approximately 2 mm deep. The trays should be kept in a bright, warm position out of direct sunlight and kept damp until germination has commenced. Seedlings can be planted out as soon as they are large enough to handle. Flowering size bulbs can be attained after 3 years from germination.
