Care notes
CultivationGrow in fertile, humus-rich, well-drained soil, enriched with organic matter, in full sun. Pinch out growing tips to encourage bushy plants and stake - see staking perennials. Water as needed in dry periods. 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
PruningDeadhead to prolong flowering. Cut back to near ground level in the autumn, before lifting and storing for the winter
PropagationPropagate by softwood cuttings taken in spring from shoots from stored tubers, or divide the tubers ensuring each division has a viable bud
Pest resistanceAphids, leaf miners, glasshouse red spider mite and slugs are common pests. Earwigs sometimes damage blooms. Capsid bug and caterpillars are occasional pests
Disease resistancePowdery mildews can be damaging in dry conditions. In wet weather grey moulds and other fungal rots can be a problem. Fungal rots can also damage stored tubers. A virus may cause stunting, leaf markings and distortion
