How to Grow

Cultivation

Grow in any well-drained soil in partial or deep shade; will tolerate a sunny position if the soil is not too dry. Mahonia don’t respond well to nitrogen rich fertilisers but do appreciate an annual mulch with well-rotted manure or garden compost in autumn. Water in very dry periods – water well if needed but not often

Propagation

Propagate by seed or by semi-ripe cuttings from late summer to autumn
