Weeping Willow (Salix babylonica)
Formerly Salix matsudana, Salix pseudolasiogyne, Salix lasiogyne
This tree grows fast and needs regular water. Give it full sun to part shade outdoors. It suits USDA zones 6a to 8b. It is a tree, not a shrub or vine. It reaches 30 to 50 ft (9.1 to 15.2 m) tall. Growers typically propagate it from stem cuttings. No cited source gives a toxicity position for cats or dogs for this species.

How much light does a Weeping Willow need?
Give your weeping willow a spot in full sun to part shade. Full sun is the preferred position, and the tree also tolerates partial shade well. This fast grower reaches a mature height of 30 to 50 ft (9.1 to 15.2 m). It also spreads 30 to 50 ft (9.1 to 15.2 m) wide at maturity.
How often to water a Weeping Willow
Weeping willow prefers abundant water and does best when the soil stays medium-wet to wet rather than dry. It tolerates soil that ranges from well-drained to occasionally wet or poorly drained. Keep the soil consistently moist rather than letting it dry out. This species is a tree rather than a shrub or vine. It survives outdoors in USDA zones 6a to 8b.
Best soil for a Weeping Willow
Weeping willow tolerates a wide range of soil drainage, including well-drained, moist, occasionally wet, and poorly drained ground. No cited source states a preferred soil pH for this species. It also prefers abundant water, doing best with medium-wet to wet soil moisture. This tree grows rapidly once planted. Growers typically propagate it from stem cuttings. Within the continental United States, this species is introduced, not native. It also does best with full sun to part shade above ground.
Hardiness and temperature
This tree survives winters in USDA zones 6a to 8b without special protection. No cited source states an exact minimum temperature for the species. It originates from parts of China and Korea, where it is native. It is classified as a tree. It can grow 30 to 50 ft (9.1 to 15.2 m) tall and spread just as wide. Within the continental United States, it is considered introduced rather than native. It is usually propagated from stem cuttings.
- Hardiness: Zones 6a–8b1
Pruning a Weeping Willow
Young weeping willows need initial pruning and training to develop good structure. Once they're established, light shaping is usually all the pruning this tree needs. Its rapid growth produces weak wood that can crack or break easily, especially in snow or ice. At maturity, this tree can reach 30 to 50 ft (9.1 to 15.2 m) tall and wide. It is grown as a tree rather than a shrub.
- Pruning: Light shaping5
How to plant a Weeping Willow
Plant weeping willow in USDA zones 6a to 8b, where it survives outdoors year-round. Choose a site with full sun to part shade and soil that stays moist to wet. Expect it to reach 30 to 50 ft (9.1 to 15.2 m) in both height and spread once established. Most growers start new trees from stem cuttings. Weeping willow is classified as a tree species.
- Hardiness: Zones 6a–8b1
Winter care
Weeping willow is hardy through USDA zones 6a to 8b without winter protection. No cited source states how cold this species can tolerate below that range. It is native to parts of China and Korea. It is a tree, not a shrub or vine. Growers usually propagate it from stem cuttings. It needs full sun to part shade outdoors. It also prefers medium-wet to wet soil moisture.
- Hardiness: Zones 6a–8b1
How to propagate a Weeping Willow
Most growers start new weeping willow trees from stem cuttings. This is a fast-growing tree. It needs full sun to part shade outdoors and medium-wet to wet soil moisture. Its flowers are silvery-green and not very showy. The species is native to parts of China and Korea.
- Propagation: Stem cuttings1
Common problems
Weeping willow attracts aphids, spider mites, leaf beetles, scale insects, borers, lace bugs, and caterpillars, along with willow leaf beetle, giant willow aphid, willow bladdergall mite, and Asian longhorned beetle. It can also develop powdery mildew, leaf spot, canker, blight, crown gall, root rot, rust, and willow scab. This is a fast-growing tree.
