How to grow Common Hawthorn

Sunlight
Full sun to partial shade
Watering
Low; very drought tolerant once established
Soil
Almost any soil, including heavy clay, chalk and poor ground
Soil pH
Acid, neutral or alkaline

Planting

The standard native hedging plant, planted bare-root between November and March at around 30 cm spacing, often in a double staggered row. It tolerates exposure, coastal wind, and just about any soil that is not permanently waterlogged.

Pruning

Trim hedges in winter to keep the following spring's blossom, or after flowering if you would rather have the flowers than the berries. It regenerates readily from old wood and can be laid in the traditional way.

Propagation

Seed needs eighteen months or more of alternating warm and cold before it germinates, so most gardeners buy in whips.

Pests and diseases

Powdery mildew and leaf spot are common and cosmetic. Fireblight causes shoots to blacken and die back as though burnt, and affected wood should be cut well below the damage.

Value to wildlife

Among the most valuable native plants for wildlife. It supports large numbers of insect species, gives dense thorny nesting cover, and the autumn haws feed thrushes, redwings and fieldfares.

Notes

As a free-standing tree it is tough, wind-shaped and long-lived. The thorns make it a genuinely stock-proof and intruder-proof boundary, but also unpleasant to prune without gauntlets.
