Flowering Dogwood is a small ornamental understory tree prized for large showy spring bracts that range from white to pink depending on the cultivar. It adds seasonal interest with spring flowers and wildlife friendly fruit while requiring sites with good drainage and some afternoon shade in hot climates.
Identification
Flowering Dogwood typically grows as a multi branched small tree about 15 to 30 feet tall and often as wide. Leaves are opposite and turn attractive fall colors. The showy structures that look like flowers are actually bracts surrounding a cluster of true tiny flowers in spring. Fruits are red drupes eaten by birds.
Where to grow and best uses
This species belongs in mixed shrub borders, understory plantings below larger trees and as a specimen in small yards where spring bloom is desired. It is hardy in USDA zones 5 to 9 and performs best in sites with some protection from hot afternoon sun. Avoid poorly drained locations to reduce disease risk.
Planting time and spacing
Planting is commonly done in spring or fall depending on local climate and soil conditions. Space trees according to mature spread with 15 to 30 feet between specimens depending on cultivar and the effect desired. Choose a planting site with room for the canopy and root system to mature without crowding.
Soil and light
Flowering Dogwood prefers moist, well drained soils that are acidic to neutral and tolerates heavier soils when drainage is adequate. It grows in full sun to part shade and benefits from afternoon shade in hot inland climates to prevent leaf scorch and stress. Strongly alkaline soils can cause decline.
Watering and routine care
Keep young trees regularly watered until established to encourage a healthy root system. Poor drainage and persistently wet soils increase risk of root rot and fungal disease while hot dry sites or full sun without afternoon shade can cause leaf scorch. Mulch the root zone to conserve moisture and moderate soil temperature.
After flowering and pruning
Remove dead or crossing branches in late winter or early spring to maintain structure and airflow. Light pruning after flowering helps preserve natural form and bloom potential the following year. Heavy pruning reduces spring bloom and should be done sparingly and only when necessary.
Pests and diseases
Flowering Dogwood is susceptible to dogwood anthracnose and other fungal problems especially in cool wet sites. Favorable practices include planting in well drained, airy sites and avoiding overhead wetting when possible. Monitor for leaf spots dieback and consult local extension services for diagnosis and control options suited to your region.
Propagation
Named cultivars are commonly propagated by grafting or cuttings to preserve specific traits. Seed propagation requires cold stratification to break dormancy. Layering and softwood cuttings are also used. Success varies by cultivar so follow specific protocols for the variety you are propagating.
Frequently asked questions
- How fast does Flowering Dogwood grow?
- Growth is generally moderate and time to reach mature height varies with site fertility climate and cultivar. Typical mature height ranges from 15 to 30 feet.
- When should I prune after flowering?
- Prune dead or crossing branches in late winter or early spring. Light pruning immediately after flowering helps keep shape without reducing next spring bloom.
- How can I reduce the risk of dogwood anthracnose?
- Plant in well drained sunny to partly shaded sites with good air circulation. Avoid overhead irrigation and remove infected wood. Consult local extension resources for recommended treatments in your area.
- What soil pH do they prefer?
- They prefer acidic to neutral soils roughly around pH 5.5 to 7.0 and can decline in strongly alkaline conditions. Test local soil and amend if needed.
- What are common propagation methods?
- Propagate by seed with cold stratification or by grafting and cuttings for named cultivars. Layering and softwood cuttings are also used and success depends on the variety.
- Are the fruits toxic to pets?
- Fruits are eaten by birds and wildlife. Ingesting large amounts may cause gastrointestinal upset in pets. Confirm pet safety with ASPCA or local poison control for definitive guidance.
