Water Meliosma arenosa regularly, especially during its active growth period in spring and summer. Allow the top inch of soil to dry out between waterings.

Reduce watering in fall and winter, providing just enough to keep the soil from becoming completely arid. Ensure good drainage to prevent root rot.

Prune Meliosma arenosa to maintain its shape and size, or to remove any dead, damaged, or crossing branches. The best time for major pruning is in late winter or early spring before new growth begins.

Lightly shape the plant as needed throughout the growing season.

Propagation of Meliosma arenosa can be achieved through seeds, which require stratification, or stem cuttings. Take cuttings in late spring or early summer from healthy, semi-hardwood growth.

Root the cuttings in a well-draining medium, keeping them consistently moist and warm.

Repot Meliosma arenosa every 2-3 years, or when it becomes root-bound. Use a well-draining potting mix, such as a blend of peat moss, perlite, and sand. Repot in spring before the active growing season commences.

Handle the roots gently to minimize transplant shock.
