Water regularly, especially during dry periods, to keep the soil consistently moist but not waterlogged. Reduce watering in autumn and winter. Young trees benefit from more frequent watering until established.

Check soil moisture before watering.

Prune in late winter or early spring while the tree is dormant to shape the canopy and remove dead, damaged, or crossing branches. Light pruning can be done in summer to control size or improve air circulation.

Avoid heavy pruning as it can lead to sap bleeding.

Propagate from seed sown in autumn or by grafting in late winter. Seeds require stratification (a period of cold, moist treatment) to germinate.

Grafting, often using Acer pseudoplatanus rootstock, is a more reliable method for achieving desired traits.

Repot young trees every 2-3 years in early spring before bud break. Use a well-draining potting mix. For mature trees, repotting is rarely necessary and can be disruptive.

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