It is prized for its striking bright-red stems that provide vivid winter color when leaves have fallen. In spring, it produces flat-topped clusters of small creamy...
Red-Barked Dogwood grows up to 3.0m, spread of 300cm, watering every 7 days, -29°C – 30°C, 30–60% humidity. It is not suitable for indoor environments and not safe for pets.
Unlike many tropical plants, Red-Barked Dogwood tolerates watering mistakes. Best for beginners. Without precautions, ingestion can cause irritation in pets. Keep out of reach of cats and dogs.
How to Care for Red-Barked Dogwood?
TLDR: Red-Barked Dogwood needs Bright indirect, watering every 7 days, and temperatures between -29-30°C with 30-60% humidity.
How Often Should You Water Red-Barked Dogwood?
Water deeply once a week during spring and summer. Established plants tolerate wet soils and short dry spells. Reduce watering significantly in autumn and winter. Avoid prolonged drought — mulch around the base to retain soil moisture.
How Much Light Does Red-Barked Dogwood Need?
Thrives in full sun (6+ hours daily) to partial shade. Full sun produces the most vivid red stem colour and best flowering. In hotter climates, afternoon shade prevents leaf scorch. Avoid deep shade, which reduces stem colour intensity.
What Is the Best Soil for Red-Barked Dogwood?
Grows in most well-drained soils — clay, loam, or sandy loam — as long as they are reasonably fertile. Amend poor soils with compost at planting. Tolerates slightly acidic to neutral pH (5.5–7.5). Can handle occasionally waterlogged conditions.
What Pot Should You Use for Red-Barked Dogwood?
Terracotta or heavy ceramic containers work well for contained planting. For garden use, no pot is needed — plant directly in the ground. If containerised, choose a large pot (at least 40 cm diameter) with good drainage holes.

What Is Red-Barked Dogwood and Where Does It Come From?
Cornus alba, commonly known as the Red-Barked Dogwood or Tatarian Dogwood, is a deciduous shrub native to Siberia and northeastern Asia. It is prized for its striking bright-red stems that provide vivid winter color when leaves have fallen. In spring, it produces flat-topped clusters of small creamy-white flowers, followed by white to bluish berries that attract birds. The dark green leaves develop beautiful reddish-purple tones in autumn, making this shrub a true four-season plant.
How to Propagate Red-Barked Dogwood?
Hardwood Cutting
Hardwood cuttings are the easiest and most reliable method. Take multiple cuttings to improve success odds. Label pots with the date.
- 1 In late autumn or winter, cut healthy stems 20-25 cm long from the previous season's growth.
- 2 Remove all leaves and cut just below a leaf node at the bottom.
- 3 Dip the base in rooting hormone powder.
- 4 Insert cuttings into a pot of free-draining compost and perlite mix.
- 5 Keep in a cool frost-free place and water sparingly until rooting occurs in spring.
Materials needed:
Ground Layering
Ground layering uses the parent plant's resources, giving very reliable results. Keep the soil around the layered area moist.
- 1 Select a low, flexible stem in spring.
- 2 Make a shallow nick or remove a small ring of bark 30 cm from the tip.
- 3 Bend the stem to the ground and bury the nicked section 5-8 cm deep.
- 4 Pin in place with a U-shaped peg or heavy stone.
- 5 Water the area regularly and sever from the parent plant once roots are established.

Powdery Mildew
Powdery mildew is a common fungal disease caused by various fungi species including Erysiphe, Podosphaera, Oïdium, and Leveillula. It affects over 10,000 plant species worldwide. The disease thrives in warm, dry climates with high humidity and appears as a distinctive white powdery coating on plant surfaces.
Leaf Spot
Leaf spot is a common fungal disease caused by various pathogens including Alternaria, Ascochyta, Colletotrichum, Septoria, and Venturia. It primarily affects leaves, causing discolored spots that can lead to premature leaf drop if left untreated.
Canker
Canker is a disease caused by various fungi and bacteria that create necrotic, sunken areas on bark of branches, stems, and trunks. Pathogens enter through wounds and natural openings, especially when plants are stressed. Canker can gradually weaken or kill branches by disrupting water and nutrient flow.
Meaning & Symbolism
