Water Cytisus aeolicus moderately during the growing season, allowing the soil to dry out slightly between waterings. Reduce watering significantly in winter to prevent waterlogging and root rot.

Ensure good drainage to avoid saturated conditions, which this plant dislikes.

Prune Cytisus aeolicus after flowering to maintain shape and encourage bushier growth. Remove any dead, damaged, or crossing branches.

Light pruning can be done to control size, but avoid hard pruning into old wood as it may not regrow.

Cytisus aeolicus can be propagated from semi-hardwood cuttings taken in summer. Root the cuttings in a well-draining medium.

Alternatively, sow seeds in autumn or spring, though seedlings may take longer to establish and can be less predictable.

Repot Cytisus aeolicus when the plant becomes root-bound, typically every 2-3 years. Use a well-draining, gritty potting mix. Repot in spring before new growth begins.

Choose a pot that is only slightly larger than the current one to avoid excess moisture retention.
