Water regularly during the first year to establish a strong root system. Once established, Koelreuteria bipinnata is drought-tolerant and requires supplemental watering only during prolonged dry spells.

Ensure good drainage to prevent waterlogging, as the tree dislikes consistently wet soil, which can lead to root rot.

Prune in late winter or early spring before bud break to shape the tree and remove any dead, damaged, or crossing branches. Pruning after flowering can remove the attractive seed pods.

Young trees benefit from structural pruning to develop a strong framework.

Propagation is typically done by seeds, which require stratification (a period of cold, moist treatment) before sowing. It can also be propagated from root cuttings taken in late winter.

Grafting is another method used to ensure desirable traits.

Repotting is rarely necessary for mature trees as they are not typically grown in containers. If a young tree becomes root-bound, repot in spring into a slightly larger container with well-draining potting mix.

Ensure the new pot has adequate drainage holes.
