How to Grow

Cultivation

Outdoors, grow in fertile, well-drained soil in full sun, with protection from cold, drying winds; against a south- or west-facing wall is ideal. Under glass, grow in peat-free, loam-based potting compost in full light with shade from hot sun. When in growth, water freely and apply a balanced liquid fertiliser monthly; water sparingly in winter

Propagation

Propagate by sowing seed as soon as ripe. Root semi-ripe cuttings in summer with bottom heat. Layer in autumn or spring
