Water Calicotome rigida sparingly once established, allowing the soil to dry out completely between waterings. During the first year, provide more consistent moisture, but avoid waterlogging.

Reduce watering significantly in winter, as the plant is drought-tolerant.

Prune Calicotome rigida after flowering to maintain its shape and size. Remove any dead, damaged, or crossing branches. Avoid heavy pruning into old wood, as it may not regrow well.

Light shaping can encourage bushier growth and more blooms.

Propagate Calicotome rigida from semi-hardwood cuttings taken in summer. Use a rooting hormone to encourage establishment. Alternatively, sow seeds in spring, but germination can be slow and erratic.

Cold stratification may improve success rates for seeds.

Repot Calicotome rigida only when necessary, typically every 2-3 years for younger plants, or when root-bound. Use a well-draining potting mix.

Choose a pot that is only slightly larger than the current one to avoid overwatering. Handle the roots gently during repotting.
