English Walnut (juglans regia)

• Long-established non-native tree, widely naturalised and well-suited to UK climates, especially southern/lowland areas.
• Produces delicious, thin-shelled edible walnuts for fresh eating, pickling (green), or cooking.
• Majestic specimen tree with broad crown providing ample shade; aromatic pinnate leaves and attractive catkins.
• Valuable timber with decorative grain for furniture; long-lived (centuries) with yellow autumn colour.
• Mild juglone effect (less than black walnut) inhibits some plants nearby.
• Supports pollinators and wildlife.
• Low-maintenance once established; suitable for large gardens, parks, or agroforestry.

Planting Guide

• Best time: Bare-root November–March (dormant season); container-grown autumn or spring.
• Location: Full sun (essential for nut production); deep, fertile, moist but well-drained soil (prefers loam, tolerates chalk/clay but dislikes waterlogged); sheltered from frost pockets and strong winds; requires vast space – matures 20–35m tall/wide, unsuitable for small gardens.
• Preparation: Dig large hole twice root ball width; add organic matter to poor soils.
• Planting: Set at original depth (check trunk soil mark); stake young trees; firm in, water well, mulch base to surpress weeds and maintain moisture.
• Aftercare: Water regularly first few years in dry spells; minimal pruning (winter for form); monitor for late frosts and protect small trees if possible; protect ripening nuts from squirrels.
