Water deeply when the top 5-10 cm of soil is dry, especially during prolonged dry spells. Allow soil to dry out slightly between waterings once established.

Good drainage is crucial to prevent waterlogging, which this plant dislikes.

Prune in late winter or early spring before new growth begins. Remove any dead, damaged, or crossing branches. Can be pruned to shape and control size, or even cut back hard to rejuvenate an old shrub.

Remove suckers to maintain desired form.

Easily propagated from seed sown in autumn or stratified and sown in spring. Cuttings can be taken from semi-hardwood in summer or hardwood in winter. It also readily spreads via root suckers, which can be divided.

Amorpha fruticosa is not typically a plant that requires frequent repotting. If grown in a container, repot only when root-bound, usually every 2-3 years, into a slightly larger pot with fresh, well-draining potting mix in spring.
