Pleaching
Pleaching is a form of living architecture. It
is an ancient art traced back to the Romans
and involves plaiting or weaving living
branches together to form a structure. In the
process of training or over time, these
branches fuse or are grafted together. This
means that the cambium layers (see pages 1
and 2) of individual plants unite forming a
self-supporting structure. The most
advanced pleaching techniques involve
exposing the cambium layers of the woven
stems; that is, removing the outer bark so
that the rich green cambium of both stems
