Inga macrophylla prefers consistently moist soil, especially during its active growth period. Water thoroughly when the top inch of soil feels dry. Avoid waterlogged conditions, as this can lead to root rot.

Reduce watering slightly during cooler months or when the plant is dormant.

Prune Inga macrophylla to maintain its desired shape and size, and to remove any dead, damaged, or crossing branches.

Light pruning can be done anytime, but heavier pruning is best performed in late winter or early spring before new growth begins. This encourages bushier growth.

Propagation is typically done by seeds, which should be sown fresh and kept moist. Inga macrophylla can also be propagated from semi-hardwood cuttings taken during the summer months.

Ensure cuttings are treated with rooting hormone and kept in a humid environment to promote root development.

Repot Inga macrophylla every 2-3 years, or when it becomes root-bound. Use a well-draining potting mix, such as a blend of peat moss, perlite, and compost.

Choose a pot that is only slightly larger than the current one to avoid overwatering issues. Repot in spring.
