Siting: Asters prefer full sun. The soil should be well drained, but maintain a moist root zone. Coarse to medium soils are ideal for this.11

Care: Plant in suitable site with adequate soil organic matter so that the crown of the plant is at the soil surface18. Ensure the soil is adequately moist immediately after planting. Keep soil moist but not soggy until plant is established. Once plant is established water deeply but infrequently whenever the soil surface is dry or almost dry 2” below the soil surface.18

Pests: Plants are relatively pest resistant if cultural preferences are met.9
