Pleaching

Pleaching or plashing is a technique of interweaving living and dead branches through a hedge creating a fence, hedge, or lattices. Trees are planted in lines and the branches are woven together to strengthen and fill any weak spots until the hedge thickens. Branches in close contact may grow together, due to a natural phenomenon called inosculation, a natural graft. Pleach also means weaving thin, whippy stems of trees forming a basketry effect.
