How often does koelreuteria paniculata need pruning?

Formative pruning for 3–5 years; then every few years as needed. Koelreuteria paniculata (golden rain tree) needs only light pruning to maintain a clean framework. In its early years, formative pruning helps establish a strong central leader and well-spaced scaffold branches. Mature trees need little attention beyond removing dead, damaged, or crossing wood. It flowers on new wood so late-winter pruning does not reduce flowering.
