Water Styrax officinalis regularly during its establishment phase and throughout dry periods. Aim to keep the soil consistently moist but not waterlogged. Reduce watering in winter when the plant is dormant.

Check the top few centimeters of soil; if it feels dry, it's time to water.

Prune Styrax officinalis in late winter or early spring while it is dormant. Remove any dead, diseased, or crossing branches. Light pruning can be done after flowering to maintain shape and encourage bushier growth.

Avoid heavy pruning as it can reduce flowering.

Propagate Styrax officinalis from seeds sown in autumn, or through semi-hardwood cuttings taken in summer. Seeds require a period of cold stratification.

Cuttings should be treated with rooting hormone and planted in a well-draining medium. Patience is key for successful propagation.

Repot young Styrax officinalis plants every 2-3 years in early spring. Established plants generally prefer to be root-bound and may not require frequent repotting.

Choose a pot only slightly larger than the current one and use a well-draining potting mix. Ensure good drainage.
