How to prune albizia julibrissin

Annually or every 2 years. Albizia julibrissin (silk tree / mimosa) benefits from light annual pruning after flowering to shape the canopy and remove dead or weak wood. It can be hard-pruned if it outgrows its space, but avoid cutting into very old wood. Prune in late spring to avoid cold-damage to new cuts.
