What Soil Mix Works Best for a Roughleaf Dogwood?

Moist, well-draining soil rich in organic matter. Good drainage is essential for Roughleaf Dogwood to prevent waterlogging, which leads to root rot and fungal issues.

How Often Should You Fertilize a Roughleaf Dogwood?

Feed Roughleaf Dogwood every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established trees in good soil often need little extra feeding, so let weak growth or pale foliage guide you.

Stop feeding by late summer so new growth can harden before winter.

Fertilizing

Where Should You Plant a Roughleaf Dogwood?

Choose a spot with full sun to part shade and moist, well-draining soil rich in organic matter. Avoid low spots where water collects after rain.

Plant container-grown or balled-and-burlapped trees in spring or early autumn, setting the root flare at soil level, and water well after planting.

How Far Apart Should You Plant a Roughleaf Dogwood?

Roughleaf Dogwood can spread to about 15 ft (4.6 m) and reach about 20 ft (6 m) tall. Space plants about 15 ft (4.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

How Do You Prune a Roughleaf Dogwood?

Prune Roughleaf Dogwood while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.

If it flowers in spring, prune right after flowering instead so you don't remove next year's buds. Never take off more than about a quarter of the tree in one year.

How Do You Care for a Roughleaf Dogwood in Winter?

Water deeply in late autumn before the ground freezes, and spread a 5–8 cm (2–3 in) layer of mulch over the root zone, keeping it away from the trunk.

Young and container-grown trees need extra protection: roots in a pot freeze much more easily than roots in the ground.

How Do You Propagate a Roughleaf Dogwood?

Roughleaf Dogwood can be propagated through softwood cuttings, seeds. Similar propagation techniques also apply to tartarian dogwood plant care, which shares the same genus.

Is the Roughleaf Dogwood Toxic to Pets and Children?

Pet safety not verified

The ASPCA does not list Roughleaf Dogwood, so we can't confirm whether it is safe for cats and dogs. Keep pets from chewing it as a precaution.

This is a general caution, not veterinary or medical advice. If your pet ate a plant, contact your vet or animal poison control.

What Pests and Diseases Affect the Roughleaf Dogwood?

Roughleaf Dogwood is susceptible to dogwood borer, scale insects, powdery mildew. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.
