Seguridad

People: The bark contains salicylates, which can cause reactions in people sensitive to aspirin.
Pets: Willows contain salicin which can be toxic to cats and dogs if ingested.
Children: The long, flexible branches can pose a strangulation risk if used for play, and the bark should not be chewed.
Contact allergens: The bark and leaves can cause mild skin irritation in sensitive individuals.
Airborne allergens: Willow pollen is a common seasonal allergen that can trigger hay fever.
Edibility: While some willow bark contains salicin, it is not considered a food source and can cause severe stomach upset.

Problemas frecuentes

Aphids — Small insects that cluster on new growth and suck plant sap.

Cómo cultivarla

Propagation: cuttings
When to plant: spring, autumn
Overwintering: Willows are generally cold hardy and do not require special winter protection. Simply prune away any dead or damaged branches in late winter.
In containers: Willows generally do not thrive in containers due to their massive root systems and high water needs.

Hardwood Cuttings

1. Take a cutting from a healthy branch in late winter.
2. Place the cutting directly into moist soil or a container of water.
3. Keep the cutting consistently wet until roots develop.

Group willows with other moisture loving plants to create a cohesive water garden ecosystem.

Buenas compañeras

Dogwood — They share similar moisture requirements and look lovely together in wet sites.
Sedge — These grasses thrive in the same damp conditions and help suppress weeds around the base.

Mantenla lejos de

Oak — Oaks prefer much drier soil and will struggle if planted in the wet conditions a willow requires.

Especies parecidas

Poplar — They share a similar preference for water and have comparable leaf shapes.

Ciencia

Native range: Found throughout temperate and cold regions of the Northern Hemisphere.
Conservation: Most common willow species are not threatened, but some rare native varieties are protected in specific regions.

Willows act as pioneers in wet habitats, stabilizing soil and providing early spring resources for emerging insects.

Value to wildlife: early nectar source, larval host plant
Pollinators: bees, butterflies, moths, beetles
Uses: ornamental landscape tree, erosion control, basket weaving material
