charlie, hack off a fairly straight branch in the springtime when it is budding, about 3 or 4 inches around. not too big. strip off and small lower branches.
dig a hole about 3 feet deep, 1 foot wide, even if it goes into the clay layer under the topsoil. give the hole a good watering, stick the branch in the hole and backfill the hole with topsoil. water again, and every so often through the summer.
hopefully it will root and next year you should begin to see new growth.
this procedure works very well for lots of plants from figs to grapes.
in nomine patri, et fili, et spiritus sancti.
