Care notes
CultivationPlant tubers 10-15cm deep in fertile, humus-rich, well-drained soil, in full sun. Cut back to near ground level in mid-autumn. In mild areas, and on well-drained soils, leave the tubers in the ground and protect with a deep, organic mulch. In colder areas, or on heavy soils, lift and store the tubers and replant in late spring after all danger of frost has passed. See dahlia cultivation and our video How to plant dahlia tubers and care tips
PruningDeadhead to prolong flowering; cut back to the ground in autumn and either lift and store for the winter or mulch well and leave in place in milder regions
PropagationPropagate from softwood cuttings in spring taken from stored tubers or divide the tubers ensuring each division has a viable bud
Pest resistanceMay be susceptible to aphids, capsid bugs, earwigs, caterpillars, slugs, glasshouse red spider mite and onion thrips
Disease resistanceMay be susceptible to a virus; tubers may rot in storage
