Water Kei apple regularly, especially when young and during dry periods. Ensure the soil is moist but not waterlogged. Reduce watering in winter when the plant is dormant.

Allow the top few centimeters of soil to dry out between waterings for established plants.

Prune Kei apple in late winter or early spring before new growth begins. Remove dead, diseased, or crossing branches.

You can also thin out crowded branches to improve air circulation and light penetration, which helps with fruit development and overall plant health.

Kei apple can be propagated from seeds, cuttings, or grafting. Seeds require stratification and can be slow to germinate. Stem cuttings taken in summer and treated with rooting hormone often root successfully.

Grafting is also effective for ensuring desired fruit characteristics.

Repot Kei apple seedlings or young plants annually or biennially in spring. Choose a pot one size larger with good drainage. Use a well-draining potting mix.

Established trees in the ground rarely need repotting; focus on root pruning only if absolutely necessary.
