About this plant
Salix repens, commonly called creeping willow, is a low-growing, spreading shrub with slender, flexible branches and narrow leaves. It is known for its ability to form dense mats, making it useful for ground cover and erosion control. This plant produces small catkins in spring and is native to Europe. It is often found in sandy or coastal areas and is valued for its tough, adaptable nature.

Watering. Water regularly during dry periods, especially when newly planted. Once established, it tolerates some drought but prefers consistent moisture.
Fertilizing. Fertilize in early spring with a balanced, slow-release fertilizer to support healthy growth. Avoid over-fertilizing, which can lead to excessive, weak growth.
Creeping willow is a hardy shrub that prefers moist, well-drained soil and full sun to partial shade. It tolerates dry conditions once established but may suffer if soil is too dry for long periods. Regular pruning helps maintain its spreading habit and prevents it from becoming too woody.

- Pollen level
- Moderate
Salix repens, also known as creeping willow, produces pollen that can cause allergic reactions in sensitive individuals, especially during its flowering season. People with pollen allergies may experience sneezing, runny nose, or itchy eyes. To reduce exposure, avoid being near the plant when it is flowering and keep windows closed during high pollen times.
Common problems
Overwatering can cause root rot, while too little water may lead to leaf browning and poor growth. Pests like aphids or fungal diseases can occasionally affect the plant if conditions are too damp or crowded.
Uses
Used as ground cover, for erosion control, and in natural landscaping. Its flexible branches have been used traditionally for weaving and basketry.
Notes
Prune after flowering to maintain shape and encourage new growth. It can spread aggressively in favorable conditions, so monitor its growth if used in garden beds.
