Lecythis zabucajo prefers consistently moist soil but dislikes waterlogged conditions. Water deeply when the top few centimeters of soil feel dry.

Reduce watering slightly during cooler periods, but never allow the soil to dry out completely. Ensure good drainage to prevent root rot.

Pruning is primarily for shaping and removing dead or diseased branches. Minimal pruning is typically needed for established trees.

If shaping is desired, prune lightly in late winter or early spring before new growth begins. Avoid heavy pruning, as it can stress the tree.

Sapucaia can be propagated from seed, though germination can be erratic and slow. Seeds should be sown fresh in a well-draining, moist medium. Grafting is also a viable method for more controlled propagation.

Cuttings are generally difficult to root.

Young Sapucaia trees benefit from repotting every 2-3 years into a slightly larger container. Use a well-draining potting mix. Repot in spring before the main growing season.

Mature trees are often best left in their containers or planted in their final location to avoid transplant shock.
