Stewartia ovata prefers consistently moist soil. Water regularly during dry periods, especially when young. Avoid waterlogged conditions, as this can lead to root rot.

Aim for even moisture, checking the top few centimeters of soil before watering.

Prune to shape the plant, remove dead or crossing branches, and improve air circulation. Best performed after flowering in late summer. Avoid heavy pruning as it can reduce flowering for the following year.

Focus on maintaining a natural form.

Propagate from seed sown in autumn or from semi-hardwood cuttings taken in summer. Seeds require a period of cold stratification.

Cuttings should be treated with rooting hormone and kept in a moist, humid environment until established.

Repot young plants every 2-3 years in early spring, or when they become root-bound. Use a well-draining potting mix rich in organic matter, suitable for acid-loving plants.

Ensure the new pot is only slightly larger than the previous one.
