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

Reduce watering in winter.

Prune to shape the plant, remove dead or diseased branches, and manage size. Heavy pruning can be done in late winter or early spring. Thinning out dense branches can improve air circulation and fruit production.

Avoid pruning in late summer to prevent stimulating new growth susceptible to frost.

Sea-buckthorn can be propagated by softwood cuttings taken in early summer, semi-hardwood cuttings in late summer, or by root cuttings. It also readily produces suckers, which can be divided and replanted.

Seed propagation is also possible but results in variable offspring.

Repotting is typically not required for sea-buckthorn as it is a woody shrub that prefers to remain undisturbed. If container-grown plants become root-bound, repot into a slightly larger container in early spring.

Ensure excellent drainage to prevent root issues.
