How-to Guide
Growing Weeping Willow (Salix babylonica)
The short answer
Weeping willow (Salix babylonica) grows fast to 30 to 40 feet tall and wide in full sun to partial shade and deep, moist soil. It is best used as a specimen at the edge of a pond, lake, or any low, water-retaining spot, and suits rain or water gardens.
Keep it well away from sewer lines and water pipes, because willow roots aggressively seek out moisture and can damage buried pipes. Its fast growth also produces weak wood that cracks in snow and ice, so it is often not recommended for small home landscapes.
Where to plant and where not to
- Light: full sun to partial shade
- Soil: deep, moist, acidic to alkaline; avoid shallow chalky soil
- Best sited at pond or lake edges and low, wet spots
- Keep well away from sewer and water lines, foundations, and septic fields
⚠ Willow roots naturally gravitate toward buried water and sewer pipes and can damage them. Do not plant near underground utilities or drain fields.
Watering and care
Weeping willow is a moisture-loving tree suited to sites that stay damp; give it a low, wet location rather than a dry one. Its rapid growth means weak wood, so prune to remove heavy branches and reduce storm breakage.
Is it right for your yard?
Because of littering, branch breakage, and disease and insect problems, weeping willow is often not recommended for typical home landscapes; reserve it for large properties with a pond or low, wet area.
