Water Ulex minor moderately when the top 2-3 cm of soil feel dry. Ensure good drainage to prevent waterlogging, as it dislikes consistently wet roots. Reduce watering during winter dormancy.

Overwatering can lead to root rot, so err on the side of caution.

Prune Ulex minor after flowering to maintain its shape and encourage bushier growth. Remove dead or leggy stems. Avoid cutting back into old wood, as it may not regrow.

Light shaping can be done in late spring to early summer.

Propagate Ulex minor from semi-hardwood cuttings taken in summer. Treat the cuttings with rooting hormone and plant them in a well-draining, sandy medium. Maintain high humidity and warmth until roots develop.

Sow seeds in autumn or spring in a cold frame.

Repot young Ulex minor plants every 2-3 years, or when root-bound. Use a well-draining, acidic potting mix. Repot in early spring before new growth begins.

Handle the root ball carefully to minimize disturbance, as they can be sensitive to root disturbance.
