Expert tips
The key tip
Cornus alternifolia prefers cool understory conditions: rich soil, consistent moisture but well-drained. Its naturally layered form is gorgeous—don't kill it with symmetrical pruning. Just guide the main branches.
The common mistake
Stressing it with too-dry conditions and direct sun: the foliage yellows prematurely and shoots scorch.
The pro's trick
At planting time, dig wide and shallow: Cornus roots spread laterally.
Care
Light exposure and planting location
Alternate-leaved dogwood prefers dappled shade or partial sun exposure to develop its finely cut foliage and characteristic branching. Position it where it receives 3 to 4 hours of light daily. Too shady a location will slow growth and reduce flowering.
Watering
Water regularly during establishment (first year) to keep the soil moist but not waterlogged. Once established, this shrub tolerates moderate dry periods well. During prolonged drought, increase watering, especially in summer.
Soil preparation and type
Prepare soil rich in organic matter by incorporating compost or potting soil at planting time. Alternate-leaved dogwood appreciates slightly acidic to neutral, well-draining soil. Avoid alkaline or overly compacted soils that slow its development.
Pruning and training
Carry out light pruning after flowering (late June) to maintain a beautiful tiered shape. Remove any badly placed or crossing branches. Strict pruning is unnecessary; this dogwood prefers to keep its natural, elegant habit.
Fertilizing
An annual application of well-rotted compost at the base in early spring is usually sufficient. A balanced all-purpose fertilizer at the start of the growing season can support vigorous growth on less fertile soils.
Pests and diseases
This shrub is very robust and seldom troubled by disease. Occasionally watch for anthracnose (in very humid climates) and remove affected branches. Good drainage and adequate air circulation prevent most problems.
Did you know?
Cornus alternifolia is called the 'pagoda dogwood' in English for its remarkable tiered and spreading architecture that extends horizontally, giving the tree an almost zen-like appearance. Native to the eastern forests of North America, this species was used in traditional Native American medicine, while its golden variegated form 'Argentea' lights up shady gardens with its white-spotted foliage.
Where to buy it
Best planted in autumn so the roots settle in before summer, or in early spring once the frost has passed. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, October, November.
