Water regularly, especially during dry periods and when fruiting, to keep the soil consistently moist but not waterlogged. Allow the top few centimeters of soil to dry out slightly between waterings. Reduce frequency in cooler months. Good drainage is crucial to prevent root rot.

Prune Baby Lime to maintain its desired shape, remove any dead, diseased, or crossing branches, and encourage a denser, bushier habit. Light shaping can be done throughout the year. For more significant pruning, such as reducing size or rejuvenating the plant, it's best to do so after the main fruiting period or in late winter before new growth emerges. This also helps manage its thorny nature.

Propagate Triphasia trifolia primarily through semi-hardwood cuttings. Take 10-15 cm cuttings from healthy, mature stems in spring or summer, removing lower leaves and dipping the cut end in rooting hormone for better success. Plant them in a well-draining, moist potting mix under high humidity. Seeds can also be used, but germination is often slow and results in variable offspring. Air layering is another effective method.

Repot young Baby Lime plants annually into a container that is one size larger to accommodate their growth. For mature plants, repot every 2-3 years or when they become root-bound, refreshing the soil. The best time for repotting is in early spring before the active growth period begins. Use a high-quality, well-draining potting mix. Ensure the new pot has adequate drainage holes to prevent waterlogging.
