Water Oncoba spinosa regularly, allowing the soil to dry slightly between waterings. Ensure good drainage to prevent waterlogged roots, especially during its active growth period.

Reduce watering in cooler months to mimic its natural dry season.

Prune Oncoba spinosa after flowering to maintain its shape and encourage bushier growth. Remove any dead, damaged, or crossing branches.

Light pruning can be done to manage size, but avoid heavy cutting as it may reduce flowering.

Propagate Oncoba spinosa from seeds sown in spring or from semi-hardwood cuttings taken in summer. Seeds may require stratification. Cuttings should be treated with rooting hormone and kept in a warm, humid environment.

Repot Oncoba spinosa every 2-3 years, or when it becomes root-bound. Use a well-draining potting mix.

Spring is the ideal time for repotting, just before the start of the active growing season, to minimize transplant shock.
