The fruits can be used in various dishes, including salads, or made into marmalades, preserves and liqueurs.

Root rot: Avoid excess moisture and make sure the soil is well-draining before planting. Avoid piling mulch around the base of the tree. Aphids, mites, scale, mealybugs, and caterpillars are also problems.
