Genista hirsuta prefers well-drained soil and is drought-tolerant once established. Water deeply but infrequently, allowing the soil to dry out between waterings. Avoid waterlogging, which can lead to root rot.

Reduce watering significantly during winter dormancy to prevent over-saturation.

Prune Genista hirsuta after flowering in late spring or early summer to maintain its shape and encourage bushier growth. Remove dead, damaged, or crossing branches.

Avoid heavy pruning into old wood, as it may not regenerate well. Light shaping can be done annually.

Propagate Genista hirsuta from seeds or semi-hardwood cuttings. Seeds can be sown in spring after stratification (cold treatment).

Cuttings taken in summer root best when treated with rooting hormone and kept in a humid, well-drained medium. Patience is key for successful germination and rooting.

Repotting is generally not necessary unless the plant becomes root-bound. Young plants may benefit from repotting every 2-3 years in spring. Use a well-draining potting mix.

Genista hirsuta prefers to be slightly pot-bound, which can encourage flowering. Handle roots with care to avoid damage.
