Plinia complanata prefers consistent moisture but dislikes waterlogged conditions. Water thoroughly when the top 2-3 cm of soil feels dry. Reduce watering slightly during cooler months to prevent root rot.

Ensure good drainage to avoid fungal issues, especially in potted specimens.

Prune Plinia complanata to maintain shape and encourage bushier growth. Lightly trim in late winter or early spring before new growth emerges. Remove any dead, damaged, or crossing branches.

For fruit production, consider pruning to improve light penetration and air circulation within the canopy.

Propagation is typically achieved through seeds, which require stratification and can be slow to germinate.

Grafting onto suitable rootstock, such as Eugenia species, is a more reliable method for establishing new plants and ensuring desirable traits. Cuttings are generally difficult to root.

Repot young Plinia complanata plants every 1-2 years, or when rootbound, preferably in spring. Use a well-draining potting mix amended with organic matter. Gradually increase pot size to avoid shocking the root system.

Mature plants may require less frequent repotting.
