Gasteria croucheri grows well as a pot or container plant on windowsills, verandas or in rocky, succulent gardens. The plants prefer partial or dappled shade. They are tolerant towards other plant species and often share their habitat with other smaller succulent plants. They thrive well on any organic feeding. The plants are not frost-tolerant but would survive light frost. Plant on the shady side of rocks or below shrubs. It can grow in a wide range of soil and also even grows well in the winter rainfall Western Cape gardens where it should be moistened during the dry summer months. It can be divided at any time of the year. Gasterias are fairly pest free, and may occasionally be attacked by the Aloe snout weevil. Overwatering will also lead to fungal infections and rot. Another attractive species to be consider for cultivation is Gasteria polita.

Propagation

Gasteria croucheri is easily propagated from division, leaf cuttings or seed. Seed can be sown during spring or summer. In cultivation, Gasteria flowers must be cross pollinated to produce seed. Capsules soon abort when not pollinated. .Sow in a sandy, well-drained potting soil in a warm, shady position in standard seed trays. Germination is within three weeks and the seedlings are slow growing. Cover with a thin layer of sand (1-2 mm), keep moist and the seedlings can be planted out in individual bags as soon as they are large enough to handle. Flowering occurs within 3-4 years. Leaves can also be placed in potting soil. After removing the leaf, let it lie for about one month in order to heal. Lay it on its side with the basal parts in the soil. It should root within a month or two and a small plant will proliferate from the base. It can be planted out as soon as it is large and firm enough to handle.
