How to Grow Red Osier Dogwood

Red Osier Dogwood is relatively easy to grow, making it suitable for gardens, hedges, and naturalized areas.

Soil and Sun Requirements

  • Soil: Prefers moist, well-drained soil but tolerates wet and clay soils
  • pH: Neutral to slightly acidic
  • Sunlight: Thrives in full sun to partial shade; full sun enhances stem color

Planting Tips

  1. Site Selection: Choose a site with consistent moisture and adequate sunlight.
  2. Spacing: Plant shrubs 6–10 feet apart to allow for full growth.
  3. Planting Depth: Dig a hole twice the width of the root ball; keep the crown level with the soil surface.
  4. Watering: Water regularly, especially in the first two years.

Care and Maintenance

  • Mulching: Apply a 2–3 inch layer of mulch to retain moisture and regulate soil temperature.
  • Pruning: Remove old or damaged stems in late winter to promote vibrant red growth.
  • Fertilization: Use a balanced fertilizer in early spring if growth appears slow.

Propagation of Red Osier Dogwood

Red Osier Dogwood can be propagated through both seeds and vegetative methods.

1. Propagation by Seeds

  • Collect berries in late summer or early fall.
  • Extract seeds and clean them thoroughly.
  • Stratify seeds for 90–120 days in cold, moist conditions.
  • Sow in a seed-starting mix and keep the soil moist until germination.

2. Propagation by Cuttings

  • Take hardwood or softwood cuttings in late fall or early spring.
  • Cut 6–12 inch stems and remove lower leaves.
  • Dip in rooting hormone and plant in a moist, well-drained medium.
  • Roots typically develop within 4–6 weeks.

3. Layering

  • Bend a low-growing branch to the ground and cover a portion with soil.
  • Keep it moist until roots form, then separate from the parent plant.

Varieties of Red Osier Dogwood

Several cultivars and varieties of Cornus sericea have been developed to suit different landscape needs:

  • ‘Flaviramea’ (Yellow Twig Dogwood): Bright yellow stems for winter color
  • ‘Baileyi’: Compact form with vibrant red stems
  • ‘Cardinal’: Intensely red stems and dense growth
  • ‘Isanti’: Cold-hardy, ideal for northern climates

Selecting the right variety depends on climate, aesthetic preferences, and garden design goals.
