Plant : Willow

Willows offer a kaleidoscope of forms and features, from the tree-like goat willow (S. caprea) with its silver catkins to the compact, rounded S. ‘Boydii’. Dwarf types like S. bockii or S. lanata add texture with woolly shoots and small leaves. Many species burst into bloom before leaf-out; the catkins can be silvery, yellow, or pale green, often on bare branches. They thrive in slightly moist, well-drained soil and are easy to propagate by taking winter cuttings.

Light

Plant in full sun for fastest growth and best catkin display. Partial shade is acceptable, especially in hotter regions.

Water

Keep soil evenly moist, especially during the growing season. Tolerates periodic wet conditions but thrives with steady watering.

Soil

Prefers fertile loam enriched with organic matter, in moist, well-draining conditions. Can tolerate moderate clay or sand.

Temperature

Very hardy to cold winters. Young shoots may benefit from light winter protection, but mature plants are resilient.

Humidity

Adaptable to most levels, though they flourish in moist air and benefit from waterside or damp-site planting.

Fertilizer

Feed with compost or balanced fertilizer in early spring to support vigorous growth and abundant flowering.

Best Placement Ideas

• Near pond or stream edges
• In mixed woody shrub borders
• As specimen or small garden tree (S. caprea, S. ‘Boydii’)
• In rockeries with dwarf types like S. bockii

Common Issues

• Root rot in waterlogged soils
• Aphids or willow sawfly on young shoots
• Weak branches prone to breakage under weight or wind
• Flower loss in pollarded or over-pruned plants before catkin season

Things to Watch Out For

• Seed fluff may create volunteer seedlings
• Rapid sucker growth from roots
• Over-pruning during winter reduces spring bloom
• Weak wood in fast-growing varieties, requiring occasional structural pruning

Propagation Tips

Take dormant hardwood cuttings in winter (6–12″), plant directly in moist soil. Many will root without assistance early in spring, forming new plants readily.

Maintenance Tips

Prune after flowering, remove any crossing or dead stems to maintain shape. Cut back overgrown pussy or dwarf types annually to encourage compact habit. For pollard forms, re-cut to framework in winter or early spring.
