Theobroma angustifolium prefers consistently moist soil. Water thoroughly when the top 2-3 cm of soil feels dry. Avoid waterlogged conditions, as this can lead to root rot.

Reduce watering slightly during cooler, less active growth periods, but never allow the soil to dry out completely.

Prune Theobroma angustifolium to maintain desired shape and size, and to remove any dead, damaged, or crossing branches.

Light pruning can be done at any time, but heavier pruning is best performed in late winter or early spring before new growth begins. Ensure clean cuts to promote healing.

Propagation is typically done through seeds, which require warmth and consistent moisture to germinate. Cuttings can also be taken from mature plants, but they may be slower to root.

Use a well-draining potting mix and maintain high humidity around cuttings to encourage establishment.

Repot Theobroma angustifolium every 2-3 years, or when it becomes root-bound, usually in spring. Choose a pot that is only one size larger than the current one. Use a well-draining, peat-based potting mix.

Handle the root ball gently to avoid damage during the repotting process.
