Water thoroughly when the top 2-3 cm of soil is dry. Reduce watering in winter, allowing the soil to dry out more between waterings. Ensure good drainage to prevent root rot, especially in cooler months.

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

Hard pruning is generally not recommended but can be done if necessary to rejuvenate an old plant.

Sophora prostrata can be propagated by seeds sown in spring or by semi-hardwood cuttings taken in summer. Seeds may require scarification or stratification. Cuttings should be placed in a well-draining potting mix.

Repot young plants every 1-2 years, and mature plants every 3-4 years, preferably in spring. Use a well-draining potting mix. Choose a pot that is only slightly larger than the current one to avoid overwatering.
