Watering

Water deeply and regularly, keeping the soil moist during the growing season.

Fertilizing

Apply a high-potassium fertilizer every 2-3 weeks during flowering.

Pruning

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

Propagation

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

Growing

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 freely in dry periods. Lift and store tubers in autumn to replant or use as a source of cuttings in spring. See dahlia cultivation
