Water regularly, keeping the soil consistently moist but not waterlogged. Allow the top 2-3 cm of soil to dry out between waterings, especially during warmer months. Reduce watering in cooler periods to prevent root rot.

Ensure good drainage to avoid overwatering issues.

Pruning is generally not required for Solanum mammosum unless to remove dead, damaged, or diseased branches. If the plant becomes leggy, light pruning in spring can encourage bushier growth.

Pinching back the tips of young plants can also promote branching.

Propagate primarily from seeds sown in spring. Sow seeds in a well-draining seed-starting mix, keeping them moist and warm (around 20-25°C). Germination can take several weeks.

Cuttings can also be taken from semi-hardwood in summer.

Repot young plants annually in spring as they outgrow their containers. Mature plants can be repotted every 2-3 years or when root-bound. Use a well-draining potting mix.

Choose a pot that is only slightly larger than the current one to avoid excessive moisture retention.
