Maerua oblongifolia prefers well-drained soil and can tolerate periods of drought once established. Water thoroughly when the top 5-7 cm of soil feels dry.

Avoid overwatering, which can lead to root rot, especially in poorly draining conditions.

Prune Maerua oblongifolia primarily to maintain its shape or remove any dead, damaged, or crossing branches. Light pruning can be done after flowering to encourage bushier growth.

Avoid heavy pruning, as it may reduce flowering and fruiting.

Propagation is typically achieved through seeds, which may require scarification or stratification to improve germination rates. Cuttings taken from semi-hardwood in late summer or early autumn can also be used, but success rates may vary.

Repot young plants every 2-3 years or when root-bound. Mature plants can be repotted less frequently, every 4-5 years, or when drainage becomes an issue.

Use a well-draining potting mix, similar to that used for succulents or cacti.
