Care notes
CultivationGrow in fertile, humus-rich, well-drained soil, in full sun; may require support, see staking (perennials). Lift and store tubers in autumn to replant or use as a source of cuttings in spring. For more advice, see dahlia cultivation and our video How to plant dahlia tubers and care tips
PruningDeadhead to prolong flowering. Cut back to near ground level in the autumn, before lifting and storing for the winter
PropagationPropagate by seed sown at 16ºC in spring, harden off and plant out when all danger of frost has passed; or propagate by division, dividing tubers in early spring, ensuring each section has a growing shoot
Pest resistanceMay be susceptible to aphids, capsid bugs, glasshouse red spider mite, caterpillars, earwigs and slugs
Disease resistanceMay be susceptible to powdery mildews and virus diseases; tubers may rot in storage in damp conditions
