Theobroma speciosum prefers consistently moist soil. Water thoroughly when the top 2-3 cm of soil feels dry, avoiding waterlogged conditions.

Reduce watering slightly during cooler, less active growth periods to prevent root rot. Ensure good drainage to maintain healthy roots.

Prune to shape the plant, remove dead or diseased branches, and improve air circulation. Lightly prune in spring after the main flush of growth. Remove any crossing or weak branches.

Avoid heavy pruning, as it can stress the tree and reduce fruit yield.

Theobroma speciosum is typically propagated from seeds, which should be sown fresh as they lose viability quickly. Germination can be slow and erratic.

Grafting is another method, often used to ensure desirable fruit characteristics and faster maturity. Maintain warmth and humidity for successful propagation.

Young plants may need repotting every 1-2 years as they outgrow their containers. Choose a pot with excellent drainage and use a well-draining potting mix. Repot in spring, preferably during active growth.

Mature trees are generally best left undisturbed in the ground.
