Growing Cornus (Dogwood) – Trees and Shrubs

Cornus (Dogwood) Growing Guide

Pronunciation: kor'nuss

Culture

Pagoda Dogwood (C. alternifolia) and variegated dogwoods prefer partial shade. Cornus canadensis in partial to full shade. Other dogwoods: full sun to part shade. Varieties grown for stem color or autumn foliage perform best in full sun. Moderately rich, well-drained soil; tolerate evenly moist but not soggy. Seldom need fertilizing. Few insect/disease problems.

Space shrubs (C. alternifolia, C. sanguinea, C. sericea) 3–5 ft apart; mature 5–9 ft tall. Trees (C. controversa, C. elliptica, C. florida, C. kousa) 10–30 ft tall; space accordingly.

Pruning

Stems of C. alba, C. sanguinea, C. sericea provide best color in full sun when cut to 12 inches every 2–3 years. Prune late January to early March in Zones 4–7, earlier further south, before sap rises. Other shrubs/trees: remove dead/weak growth, shape as needed in early spring.

Growth

C. florida and C. alternifolia slow initially, then moderate. C. kousa slower. Others may grow 25+ inches/year in good conditions.

Suggested Use

Plant shrubs/trees behind perennials, in shrub border, along roadside or pond. C. canadensis lovely as groundcover or in wildflower garden.
