Water moderately during the active growing season, allowing the soil to dry slightly between waterings. Reduce watering significantly during dormancy in winter.

Ensure good drainage to prevent root rot, as Protea amplexicaulis is sensitive to overwatering. Avoid waterlogging at all costs.

Prune lightly after flowering to remove spent flower heads and shape the plant. Avoid heavy pruning into old wood, as Protea amplexicaulis may not regrow.

Aim to maintain a natural, open form, encouraging air circulation which helps prevent fungal diseases.

Propagate from semi-hardwood cuttings taken in late spring or early summer. Use a rooting hormone and plant in a well-draining, sandy medium. Maintain high humidity and warmth until roots form.

Germination from seed is possible but challenging and slow.

Repot only when necessary, typically every 2-3 years, to refresh the soil and prevent the plant from becoming pot-bound. Use a gritty, well-draining potting mix, similar to what is used for cacti and succulents.

Repot in spring, handling the root ball gently.
