Water newly planted Mediterranean Spurge regularly until established, typically for the first year. Once established, it is highly drought-tolerant and requires minimal watering, especially in winter.

During prolonged dry spells in summer, occasional deep watering may be beneficial, but avoid overwatering as it can lead to root rot. Ensure excellent drainage.

Prune Mediterranean Spurge after flowering, typically in late spring or early summer, to maintain its shape and prevent excessive self-seeding.

Cut back spent flower stalks to the base of the plant or to a strong side shoot. Wear gloves and eye protection when pruning due to the irritating sap. Remove any dead or damaged stems as needed.

Mediterranean Spurge can be propagated by seed or by basal cuttings. Seeds can be sown in autumn or spring, often self-seeding readily in the garden.

For cuttings, take non-flowering shoots in late spring or early summer, dip the cut end in water to stop sap flow, then in rooting hormone, and plant in a well-draining mix.

Repotting is generally not a frequent requirement for Mediterranean Spurge, as it prefers to be somewhat root-bound and is often grown in the ground.

If grown in a container, repot every 2-3 years into a slightly larger pot with fresh, well-draining potting mix. This is best done in early spring before new growth begins.
