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.
Could it be this simple? hmmmm The living willow fence- In short, you take long and straight willow stems and plant then in a line in the spring (just stick them in the ground), weaving them into a desired form and tie joints together for stability for the first few years for stability (elastic is good for this, but will need to be removed eventually).
