How to Grow

Cultivation

In colder areas, grow in containers in peat-free, loam-based compost, water freely when in growth but sparingly in winter, and apply a balanced liquid fertilizer monthly from spring until flowering; in milder areas, grow outside in moisture-retentive but well-drained soil in full sun, in a sheltered position such as a south-facing or wet-facing wall, and provide winter protection with a dry mulch; for more advice, see Agapanthus cultivation

Propagation

Propagate by division in spring
