Water regularly during the first year to establish the root system. Once established, Genista tinctoria is drought-tolerant. Water deeply but infrequently, allowing the soil to dry out between waterings.

Avoid waterlogged conditions, which can lead to root rot.

Prune after flowering in late summer or early autumn to maintain shape and encourage bushiness. Remove any dead, damaged, or crossing branches.

Light pruning can also be done in early spring to remove winter damage and shape the plant. Avoid heavy pruning into old wood.

Propagate by sowing seeds in autumn or early spring. For vegetative propagation, take semi-ripe cuttings in summer or hardwood cuttings in late autumn.

Root cuttings in a well-draining compost mixture, keeping them moist and in a sheltered location.

Genista tinctoria generally prefers to be slightly pot-bound and does not require frequent repotting. If repotting is necessary, do so in early spring before new growth begins. Use a well-draining, sandy compost mixture.

Handle the roots gently to minimize disturbance.
