🪴 Cultivation

Prefers fertile, moist, well-drained soils in full sun; tolerates drier Cerrado ground. Propagated by seed, germinating in 5–10 days (>80% rate) in a light, well-lit substrate; seedlings field-ready within a few months. Cultivated trees flower from about 3 years old.

✂️ Management & Pruning

Formative pruning only when young, to train the trunk; a slow-growing climax species that does not resprout vigorously — avoid hard pruning.
