Can this be done successfully with dwarf fruit trees.A friend of mine has several apple dwarf apple trees (will reach 10'x10') and really not enough room for them.We could easily put up a couple wires for supports.Just not sure if it can be done.
For espalier, you can use dwarf or semi dwarf rootstocks like M9, M7 or M26. More information here : http://en.wikipedia.org/wiki/Malling_series and here (in French) http://www.oxadis.com/front/process...dito_suite&idobj=5513&idpere=5502&idfils=5502
