New England aster 'Violetta'

Grow in rich, fertile, moisture-retentive soil, in full sun if the soil remains moist throughout the growing season, or in partial shade; mulch every year after cutting down in late autumn. As one of the taller cultivars, it may require support - see staking perennials

No pruning required, except cutting stems close to the ground in late autumn

Propagate by division in spring; regular division helps to keep plants healthy and vigorous but is only necessary every few years

May be affected by eelworm, aphids, slugs, and snails

May be affected by Fusarium foot rot, leaf spot, grey moulds, Verticillium wilt and powdery mildews
