How to Grow and Care for Corkscrew Willow

The main appeal of the corkscrew willow are its drooping, twisted, contorted twigs. They start out slender and olive-green in color and mature to gray-brown. Like the twigs, the leaves are often twisted. The bark is gray-brown, with diamond-shaped lenticels when the tree is young. The bark becomes shallowly fissured when mature. The shiny green foliage is simple, alternate, narrow, oval-shaped, and finely serrated.

Fuzzy pale yellow-green flowers (catkins) appear in early spring with the leaves. They turn into small light brown fuzzy capsules that contain many small fuzzy seeds. The leaves turn yellow in the fall and once they've dropped, the twisted twigs become even more apparent, which lends the tree special winter interest.

Plant a corkscrew willow any time during the spring or summer. Moist soil and ample space are prerequisites, as it is tall and easily reaches a spread of 20 feet, sometimes even more. It is a fast-growing tree but that comes with a caveat—corkscrew willow is short-lived. Expect to replace it within 15 to 20 years. In ideal conditions it might last 30 years.

Corkscrew Willow Care

Like all willows, corkscrew willow needs water to thrive. If the soil isn't naturally moist, making sure that it gets sufficient water is the most important thing when taking care of the tree.

Apply a two to three-inch layer of mulch a couple of inches away from the base. Mulch will maintain moisture and keep weeds down. A large circle of mulch around the tree not only helps to retain moisture in the soil, it also creates a buffer so you don't damage the tree when trimming around the tree or mowing the grass, as the the wood is weak and prone to mechanical damage and breakage.

Other than pruning to remove dead branches and ensure good airflow, the tree requires little maintenance.

The tree is best planted in a sunny location. Corkscrew willow prefers full sun, though it will also grow in part shade to part sun.


Corkscrew willow isn't very particular about the soil type; it can grow in clay, loamy, and sandy soil but it must be moist. The tree is equally adapted to a wide pH range, from acidic to alkaline (5.6-7.8).


While corkscrew willow is more drought-tolerant than other willows, it does have special water needs. To cut down on frequent watering, plant it in a location where the soil is moist most of the time, such as in the lowest part of your garden, where water collects after it rains, or in a rain garden.

Temperature and Humidity

Corkscrew willow is a hardy tree that is well-adapted to cold temperatures. It does not fare as well in a hot, humid climate.


When planted near or as part of a fertilized lawn, there is usually no need to fertilize the tree, unless the new growth seems weak. One cup of balanced slow-release fertilizer in the spring when the growing season starts is enough to give it a boost.

Varieties of Corkscrew Willow

There are two willow cultivars with similarly twisted twigs:

  • 'Golden Curls’, a naturally occurring cultivar with weeping, twisted golden twigs
  • 'Scarlet Curls', a trademarked cultivar with golden twisted twigs that turn scarlet in the winter, as well as curly leaves


Prune in late winter to early spring. When damaged or dead branches are pruned annually, the tree will stay healthy, let air and sunlight in, and make it less prone to insect damage.

Propagating Corkscrew Willow

The recommended method to propagate corkscrew willow is from hardwood cuttings when the tree is dormant, after the leaves have fallen in autumn and temperatures are consistently below 32 degrees Fahrenheit at night. Propagation from seeds is not advised, as it won't produce a tree true to type.

  1. Take cuttings from the base of a mature tree. The cuttings should be all hardwood with no soft tissue and at least 2 feet long.
  2. Make a straight cut at the base of the cutting below a bud, and a second, diagonal cut at around 9 inches, above a bud (you'll get two cuttings out of one piece).
  3. Place cuttings directly into the soil with the straight cut down, about 4 inches deep in the ground. Mark the location well. A more controlled way of rooting the cuttings is to plant them in pots filled with potting mix, also 4 inches deep. Dipping the cuttings in rooting hormone is optional, as willow often roots on its own.
  4. Keep the soil evenly moist. You should see new shoots in the spring. Let the saplings develop strong roots for at least one growing season before transplanting.

Potting and Repotting

Due it its large size and fast growth rate, the tree is not suitable to be grown in containers.


Corkscrew willow is winter-hardy to USDA zone 4 and does not require any overwintering protection. 

Common Pests and Plant Diseases

Corkscrew willow is susceptible to many pests and diseases but they don't necessarily endanger the tree. The most lasting pests are willow leaf beetles, which go through two generations per year. Adult beetles are metallic blue and eat the whole leaf. The black larvae they leave behind skeletonize the leaves. Typically, willow leaf beetles will not damage all the foliage and the tree will continue to thrive.

Aphids will cause honeydew to appear on lower leaves. Fortunately, predatory insects can deter such pests naturally. If the leaves begin to yellow, this could be a sign of lace bugs. These winged transparent insects are small and found under the leaves, which will turn yellow too early in the season.

Of the fungi that can attack corkscrew willow, powdery mildew is the most widely known. Another fungus is willow scab, which enters twigs and causes cankers, killing young leaves quickly. The fungus can be detected as olive green spores on the underside of leaves. Physalospora miyabeana is another fungus that attacks willow. Yellow spots under the leaves could be a sign of rust, another fungus.

To maintain the tree's health, prune infected branches as soon as you notice them. Rake up and remove diseased leaves at the end of every growing season to break the disease cycle.

Common Problems with Corkscrew Willow

The roots of corkscrew willow grow close to the surface and can be quite aggressive. This is important to keep in mind when selecting a planting site. Do not plant the tree near structures, water drainage systems, or pipes.

  • Is corkscrew willow the same as curly willow?

    The two are the same. Curly willow is another common name for Salix matsudana.

  • Where are corkscrew willows native?

    The tree is native to China and Korea. 'Tortuosa' is a cultivar that was introduced from China to the United States in 1923.

  • What's the difference between weeping willow and corkscrew willow?

    Corkscrew willow has an upright growth habit and twisting twigs whereas weeping willow has straight branches that bend downwards.
