How to Grow a Corkscrew Willow Tree
The corkscrew willow (Salix matsudana 'Tortuosa') is fast growing and part of the Salicaceae family. It is also known as the dragon's claw willow, hankrow willow or pekin willow. The unusual growth of the tree includes twisting branches rising upward and then out. This small to medium tree is not native to North America but grows well in USDA hardiness zones 4B through 8A. The corkscrew willow can reach heights of 30 feet with a canopy of up to 15 feet. Does this Spark an idea?

1
Select a location to plant a corkscrew willow tree that provides enough room for its mature height and spread. Pick a site with full sun to partial shade and well-drained soil.
-
2
Cultivate the area to a depth of one foot using a shovel (or rototiller). Extend the cultivation out to at least two and up to five times the width of the corkscrew willow rootball. This allows the roots to spread out more easily. Dig a hole in the center of the cultivated ground the same depth as the tree's container and with sloping sides.

3
Carefully remove the tree from the container and inspect the rootball. Untangle, loosen or cut off any damaged, circling or broken roots.
-
4
Place the corkscrew willow tree in the center of the hole. Check the height and add or remove soil, if needed to keep the rootball at the same height relative to the surface of the ground as it was planted in the container (or slightly higher to allow for settling).
-
5
Backfill the hole one-third full and press the soil gently to pack it around the rootball. Fill the hole with a few inches of soil and then add water to settle it. Keep adding the soil and water until the hole is filled.
-
6
Create a wall, or berm, at least four inches high and as wide as the canopy of the tree around the planting hole with the extra soil. This will help retain water for the roots when you water the corkscrew willow tree.
-
7
Add a two- to four-inch layer of mulch extending out three feet from the corkscrew willow tree in all directions. Keep an area around the base of the tree clear of mulch. The mulch prevents weeds in the area and helps keep the soil moist.
-
8
Fill the watering basin inside the berm full with water. Continue to supply water this way at least weekly throughout the growing season, if it does not rain. Check the soil under the mulch, and water when it is dry.
