Dogwood Growing Guide

Cornus species, Cornus florida, Cornus nuttallii, Cornus kousa, Cornus stolonifera, Cornus sericea

Crop Rotation Group

Miscellaneous ●

Soil

Moist, well-drained soil enriched with plenty of compost or other organic matter.

Position

Full sun to part shade.

Frost tolerant

Cold hardiness varies with species, but most dogwoods can tolerate cold to -20°F (-29°C). Pacific dogwood is less cold tolerant, while shrubby red-osier dogwood survives arctic cold but has a low tolerance for summer heat.

Feeding

None generally needed.

Spacing

Single Plants: 2' 11" (90cm) each way (minimum)
Rows: 2' 11" (90cm) with 2' 11" (90cm) row gap (minimum)

Sow and Plant

Set out purchased plants in spring at about the time of your last frost. Container-grown plants can be transplanted until early summer, but may shed some leaves if set out under stressful conditions. Water young plants regularly, and cover the root zone with an organic mulch to keep the soil moist at all times. Dogwoods become more drought tolerant after the plants are well rooted. The spacing shown is for tightly-grown hedges. However, dogwoods are usually grown as single specimens. When multiple trees are planted, allow 20 feet (6 m) between plants. Space red-osier dogwood 5 feet (1.5 m) apart when planting them as a hedge.

Notes

Native to the southeastern US, flowering dogwood is a multi-talented tree, featuring white or pink spring flowers, red berries, and red autumn color. Many heavy-flowering cultivars are available. Pacific dogwood is a larger tree adapted to the western US. Kousa dogwood, from Asia, blooms later than flowering dogwood, and is more resistant to disease. Many shrubby dogwoods produce berries for wildlife. Red-osier dogwood is especially popular because its branches turn bright red in late winter, providing beautiful contrast against white snow.

Harvesting

Dogwood branches make stunning cut flowers, especially when combined with azaleas and other spring-blooming shrubs. Slow-growing hardwoods, dogwood trees need little pruning beyond trimming off broken or dead branches whenever they appear. Be light-handed when pruning flowering dogwoods, because their natural lateral branching pattern is part of their appeal. Buds for spring’s flowers are present in fall, so avoid pruning in winter.
