Care tips

Planting

Common dogwood (Cornus sanguinea) is a robust native shrub that tolerates a wide range of conditions, making it straightforward to establish. Plant bare-root or container-grown specimens between October and March, avoiding periods when the ground is frozen or waterlogged. December and February are ideal for bare-root stock, while container plants can go in at any time during the dormant season. Choose a site in full sun, partial shade, or even full shade—this adaptable shrub copes with all three, though autumn stem colour will be most vivid in sunnier positions. It thrives in loam, clay, or chalky soils and tolerates heavy, moisture-retentive ground better than most shrubs, making it useful for awkward damp spots. Prepare the planting area by removing weeds and digging in organic matter if your soil is very poor or free-draining. Dig a hole twice the width of the root ball and roughly the same depth. Position the shrub so the top of the root ball sits level with the surrounding soil—planting too deep can lead to stem rot. Backfill with the excavated soil, firming gently with your heel to eliminate air pockets. Space plants 250 cm apart if you're creating a hedge or informal screen; for a single specimen, ensure neighbouring plants won't crowd it as it matures to 200–400 cm in both height and spread. Water thoroughly after planting, even in winter, to settle the roots. Apply a 5–7 cm layer of well-rotted compost or bark mulch around the base, keeping it clear of the stems themselves. No staking is usually necessary unless planting in an exceptionally exposed site.

Pruning

Common dogwood requires minimal pruning if grown as a naturalistic shrub, but regular cutting keeps it compact and encourages the bright red winter stems for which it's valued. Prune in March, just before new growth begins, when you can see which stems are dead or damaged and the risk of hard frost has largely passed. For young plants in their first two or three years, remove only dead, damaged, or crossing branches to establish a balanced framework. Once mature, decide whether you want a large, informal shrub or a more controlled display of colourful stems. If you're after vivid winter colour, cut back around one-third of the oldest stems to within 5–10 cm of the ground each March. The youngest stems (one or two years old) have the brightest red bark, so this rotation keeps the display fresh. Use sharp bypass secateurs for stems up to pencil thickness and a pruning saw for anything thicker. If the shrub has become overgrown or leggy, you can renovate it by cutting the entire plant down to 15–20 cm above ground level in March. It will regenerate vigorously from the base. This hard pruning (coppicing) can be done every few years or annually if you want a compact, multi-stemmed thicket. Common dogwood flowers on the previous year's wood, so heavy annual pruning will reduce flowering and berries. If wildlife value matters more than stem colour, prune lightly or not at all, removing only dead wood and thinning congested growth every two to three years.

Maintenance

Common dogwood is a low-maintenance shrub once established, tolerating neglect better than most ornamentals. Water newly planted shrubs regularly during their first spring and summer, especially in dry spells, to help roots establish. After the first year, watering is rarely needed except during prolonged drought; the plant's moderate water requirement and tolerance of heavy soils mean it copes well with typical British rainfall. Feed in March or April by scattering a handful of general-purpose granular fertiliser (such as Growmore or blood, fish, and bone) around the base and lightly forking it into the soil surface. A top-up mulch of garden compost or well-rotted manure in March also provides slow-release nutrients and helps suppress weeds. Avoid high-nitrogen feeds, which promote soft growth at the expense of stem colour. This shrub is fully hardy (zone 4a–8b) and needs no winter protection. In fact, winter is when it earns its keep: the bare red stems are most striking from November to February. No special overwintering measures are required. Pests and diseases are uncommon. Occasionally aphids cluster on soft shoot tips in late spring, but these rarely warrant treatment and are quickly dealt with by ladybirds and other predators. Leaf spot fungi can cause cosmetic browning in damp summers, but this doesn't affect plant health. Remove and bin affected leaves if it bothers you; good air circulation helps prevent it. Renew the mulch layer each spring, keeping it clear of the stems to avoid rot. That, an annual prune if desired, and a light feed are all this undemanding native requires.
