Locate a sturdy tree with good rootstock to clone the bud.
Use a budding knife to cut a T-shaped slit in the bark of the rootstock tree. You can either make two slits, one vertical and one horizontal in the shape of a T, with a small flap to insert the bud. You can also rotate the budding knife in one perpendicular motion to make a flap
Cut the bud wood from the parent tree. Insert the knife into the bark of the tree about 1/2-inch above the bud and cut a length of wood to about 1/2-inch below the bud. Take the bud out attached to a sliver of bark called the bud shield.
Put the bud into the flap cut from the rootstock tree, sliding it down to the end of the flap.
Secure the bud with a budding rubber or tape and wrap it tightly over the bud shield or the bark backing of the bud. Do not cover the bud with the rubber or tape.
