"How to make a living willow hedge" ~ Almost all willows take root very readily from cuttings. Young, thin willow cuttings are known as withies, longer willow rods are known as whips. 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.
Fence. Planted with living stems of willow ( length 2.5 m diameter > 1.5 cm) stem height 1.2 m diamenter 20 cm - 2 rods per planting hole - a straight and a bent, alternately to the left once, the right once, bind joins with string or reeds etc. Bamboo can be used instead of willow - Just make sure it is quite dry.
Willow hurdles are used for weaving around the edges of areas in the garden, particularly raised beds. Use live willow and leave it for a few weeks to die (it will still be flexible to use) before weaving it. You will also need uprights - hazel is a good material to use .
