Water thoroughly after planting and then sparingly. Genista acanthoclada is drought-tolerant once established. Allow the soil to dry out between waterings to prevent root rot.

Reduce watering significantly during winter dormancy.

Prune after flowering to maintain shape and encourage bushier growth. Remove dead, damaged, or crossing branches at any time. Heavy pruning should be avoided as it may not tolerate it well.

Shaping can be done to keep it compact.

Propagation is typically done by seed, sown in spring. Scarify seeds before sowing to improve germination rates.

Cuttings taken from semi-hardwood in summer can also be used, but are often less successful than seed propagation.

Repotting is rarely necessary as Genista acanthoclada prefers to be root-bound. If it becomes essential, do so in spring before new growth begins.

Use a well-draining potting mix and a pot only slightly larger than the current one.
