About this plant
Salix viminalis, commonly called common osier, is a type of willow known for its long, slender branches and narrow leaves. It is often used for basket weaving and erosion control because of its flexible stems and strong root system. This plant grows quickly and can reach several meters in height, making it useful for creating natural screens or windbreaks.

Watering. Keep soil consistently moist, especially during dry periods. Avoid waterlogging, which can cause root rot.
Fertilizing. Apply a balanced fertilizer in early spring to support vigorous growth. Additional feeding is usually not necessary if the soil is fertile.
Salix viminalis is a fast-growing shrub or small tree that prefers moist soil and full sun to partial shade. It is fairly hardy but can suffer if the soil dries out too much or if it is planted in deep shade. Regular pruning helps maintain its shape and encourages healthy growth.

Toxicity & Safety

Allergy information
Salix viminalis, also known as common osier, produces pollen that can cause allergic reactions in sensitive individuals, especially during its flowering season. People who are allergic to tree pollen may experience sneezing, itchy eyes, or runny nose. To reduce exposure, avoid being near the plant when it is flowering and keep windows closed during high pollen times.
Common problems
If overwatered, the roots may rot; if underwatered, leaves can wilt and drop. It may also be affected by pests like aphids or fungal diseases if air circulation is poor.
Uses
Used for basket weaving, erosion control, ornamental planting, and as a fast-growing hedge or windbreak.
Notes
Prune annually in late winter or early spring to remove old wood and encourage new shoots. It can be propagated easily from cuttings planted directly in moist soil. Avoid planting in very dry or shaded areas.
