You can call them willow hedges but maybe a more accurate term? “Fedges” = fence + hedge. Willows, sallows, and osiers form the genus Salix (Latin for willow), a grouping of 400-ish species of deciduous trees and shrubs. Willow are native to moist soils in cold and temperate regions of the Northern Hemisphere. Almost all willows take root very readily from cuttings. Young, thin willow cuttings are known as withies, longer willow rods are known as whips.
Why a Willow Hedge?
Willow is often used for streambank stabilization (bioengineering), slope stabilization and soil erosion control. Willows are often planted on the borders of streams so their interlacing roots protect the bank against the action of the water. Their roots are often much larger than the stem that grows from them. See how to plant willow cuttings to prevent erosion at a streambank: www.ksre.ksu.edu
How to Build a Willow Hedge
Simply make a hole in the ground with a metal bar, then insert the willow cutting. Weed control is important when starting a willow fedge and the cuttings should be planted into a weed barrier that allows water penetration, otherwise the weeds might suck away a bit of vitality from the young willows. As a general rule, shorter cuttings establish and grow best without competition from weeds, whereas longer cuttings have more stored energy and can handle a bit of competition. Willows prefer full sun but will accept part shade. Willows are also very adaptable as per water conditions once they are established and will also survive in poor quality soils.

Living willow fence at Vevey Garden, Switzerland. Willow rods are pushed into the ground at an angle. The tops are tied to a horizontal, weaved in withy to give stability along the top. Willows have high levels of auxins, hormones that promote rooting success. The hormone is so prevalent that “willow water” brewed from willow stems, will encourage the rooting of many other plant cuttings as well. Image by Barbara, OvertheMoon www.flickr.com
The angled rods tend to sprout along their entire length, while the uprights oft times sprout from the top only. Botanical Gardens of Wales. Photo by Libby, www.flickr.com
Living willow hedge panels by Green Barrier of Scotland. Living hedge sections come in pre-constructed 1m widths and in heights from 1.2 to 2.5m. They are planted directly into topsoil to a depth of 60cm (2 feet), to provide support while the roots grow. www.esi.info
Use Salix Viminalis and rub off the new shoots on the lower portions of the rods to achieve this open look. Image: livingwithtwistedwillow.blogspot.com

A wood frame with tall, straight willow branches stuck vertically into the soil and intertwined into the frame. Caution, willow roots are aggressive in seeking out moisture; for this reason, they can become problematic when planted near cesspools or drainage areas. They should also not be planted close to a building due to their roots aggressive and large size. modmissy.com
Buying Willow Hedge Materials
One of the best places to find willow tree cuttings for sale is on eBay, where you’re often buying direct from the tree’s owner.
Maintaining Your Willow Hedge
The living fedge structure will require periodic pruning and weaving of new growth. By Green Barrier Fence, Europe and Canada. www.lesecransverts.ca
“During the summer any side-shoots are rubbed off to keep the lattice work of the fence clear of growth, but the top three or four buds are allowed to grow out. These shoots are trimmed back to the top of the fence in the winter.” From Living with Twisted Willow. livingwithtwistedwillow.blogspot.com
Living willow fence by Wassledine, Bedfordshire, UK. Additional cuttings can be added to secure the base. As they grow the lower shoots can also be woven in to thicken the fence. www.wassledine.co.uk
Heavy pruning at the top encourages growth at the bottom.

A rose in front of Hakuro Nishiki or Dappled willow. This is just a shrub not a fedge, added here because this willow variety is striking. The slender leaves emerge as glossy bright pink, then mature into a white, green and pink variegation. Regular pruning encourages the best color. Stems are red in the winter. Prefers moist soils.

The Willow Palace
In 1998, natural artist and architect Marcel Kalberer created the Auerworld Palace, a pavilion made of living willow trees. It is also known as the “mother of all willowpalaces”. It has become a tourist attraction for the region between Weimar and Naumburg, Germany. www.arcprospect.org

Deer will eat willow when there is nothing else to eat. But if you desire your edge trimmed periodically this might not be a bad thing. Willow rebounds quickly. Salix purpureas is the most bitter and therefore least-eaten willow.
