Care Guide

Cultivation

Grow in fertile, humus-rich, moisture-retentive soil in full sun, and every autumn add a thick mulch of organic material to help preserve soil moisture

Pruning

Deadhead to prolong flowering; cut down to the base in late autumn and remove the cut stems, to reduce the risk of eelworm and mildew the following year

Propagation

Propagate by division in autumn or spring, by basal cuttings in spring or by root cuttings from early autumn to spring; root cuttings are the best method to ensure healthy plants

Pests

Generally pest-free but may be affected by slugs, snails, aphids, and phlox stem eelworm

Diseases

Generally disease-free but may be affected by crown gall, leafy gall, fungal leaf spot and verticillium wilt; said to have good resistance to powdery mildews
