Lachenalia fistulosa is very easy to grow and a rewarding species to grow as a pot subject. The soil medium should be fairly well-drained and consist of about half coarse washed sand and half finely sieved compost. Use this mixture to fill the lower two-thirds of the pot. The upper third should be pure sand (with no loam or compost) into which the bulbs are planted. This layer stays relatively dry, preventing the bulbs from rotting if they should get too wet, while the roots can safely penetrate the richer moister organic medium below. Place the pots in full sun where the plants will grow very happily outside during the winter months, providing the temperature does not drop below freezing. In summer, the bulbs should be kept dry, preferably in a cool position. One can either lift the bulbs and store them in paper bags or store them in their pots. They perform well if they are repotted every 2-3 years with fresh soil medium.

They are easily propagated by leaf cuttings, which can be removed from the plant by slicing them at the base of the leaf blade. Half bury these leaves in a very coarse, free-draining sandy medium and leave them in a cool place out of direct sunlight. Keep the soil relatively dry to prevent the leaves from rotting, while keeping the humidity quite high — humid air and dry soil is the trick. Within a few months, small bulbils will appear along the cut edge at the base of the leaf. Eventually the leaf will wither but the bulbils can be planted like normal bulbs the following season. Flowering will take 1-2 years.

They are also easily raised from seed, which should be sown in autumn in a similar medium used for cultivation with a thin layer of sand placed over the seed. Water them gently but regularly in the first few weeks. The seedlings should germinate within about 2-3 weeks. Flowering will take 2-3 years.

Lachenalia fistulosa doesn't have many pests apart from snails and caterpillars (which can be removed by hand) and mealy bug which should be treated with a systemic pesticide. A rust fungus can be problematic and appears as orange blotches on the leaves, often developing where a leaf has been damaged by hail, for example. This is easily preventable (which is preferable) and treatable with common fungicides.

Not much fertilising is required for these bulbs, as they are not generally very demanding, but they would respond well to small doses of a diluted low-nitrogen liquid fertiliser.
