How to grow

Cultivation

Grow in fertile, humus-rich, moist but well-drained soil, in full sun. Pinch out growing tips to encourage bushy plants and stake taller dahlias, see staking perennials. Water in dry periods if needed. Lift and store tubers in autumn to replant, or use as a source of cuttings, in spring. See dahlia cultivation, and our video How to plant dahlia tubers and care tips

Propagation

Propagate by softwood cuttings taken in spring from shoots from stored tubers, or divide the tubers ensuring each division has a viable bud

Deadhead spent flowers to encourage further flowering. Cut back to near ground level in autumn, before lifting and storing for the winter
