Water Myrciaria cuspidata regularly, keeping the soil consistently moist but not waterlogged. Allow the top 2-3 cm of soil to dry out slightly between waterings, especially during drier periods.

Reduce watering frequency during cooler months when growth slows.

Prune Myrciaria cuspidata to maintain shape, remove dead or crossing branches, and encourage fruit production. Light pruning can be done anytime, but heavier pruning for structure is best done in late winter or early spring before new growth begins.

Propagate Myrciaria cuspidata through seeds, which require stratification, or by semi-hardwood cuttings taken in summer. Seeds can be slow to germinate.

Cuttings offer a faster route to established plants, rooting best in a well-draining medium.

Repot young Myrciaria cuspidata plants every 1-2 years in spring, or when root-bound. Use a well-draining potting mix.

Mature plants can be repotted less frequently, perhaps every 3-4 years, or top-dressed with fresh soil.
