Growing Conditions
Silky dogwood thrives in well-drained, moist acidic soil and can tolerate all light levels. It prefers cool, moist roots in the summer, with a layer of mulch to protect the rootbed.
Silky Dogwood Care
Light
While silky dogwood does best in part sun, it can tolerate full shade and full sun with plenty of water to keep the soil moist in full sun positions.
Soil
Growing in slightly acidic soil (pH 5-7) that is well-drained and rich in organics will help the shrub thrive and produce abundant blooms, fruit, and color.
Water
Watering is essential for young plants until they are established. Newly planted shrubs should be watered weekly and deeply for the first year. Once established, they do not require extra water unless facing drought or in full sun.
Temperature and Humidity
Silky dogwoods are frost hardy and thrive in USDA zones 5-8. Protection from high temperatures in summer is beneficial, as the shrub does not tolerate drought well.
Fertilizer
No need to fertilize this shrub, as it will grow well on most soils. If the soil pH is high, an amendment can be added to increase acidity. However, due to its role as a food source for pollinators, fertilizers and amendments are not recommended.
Types of Silky Dogwood
- C. amomum ‘Indigo’
- Cornus obliqua
- Red-osier dogwood (Cornus sericea)
Pruning
Regular pruning is essential to maintain the health and appearance of the silky dogwood. This helps to promote new growth, denser growth, and shape the shrub. Heavy pruning is best done during the dormant season or early spring.
Propagating Silky Dogwood
Silky dogwood can be propagated through layering, cuttings, and seeds. Layering and cutting are the quickest methods, with layering being the easiest.
How to Grow Silky Dogwood From Seed
Silky dogwood seeds can be collected in the fall and sown directly outdoors or cold-stratified in the refrigerator for 12 weeks before starting indoors.
Overwintering
Cold hardy down to USDA zone 5, silky dogwood drops its leaves in the fall and goes dormant. It generally handles winter weather well.
