So, what to do when pruning the fruit tree next time? Don't throw the branch away, try the drafting or budding technique, who knows probably miracle will happen ;-)

According to Rothenberger and Starbuck @ UM, most varieties of a particular fruit or flowering species are interchangeable and can be grafted. Grafting techniques can be divided into two basic types, which are largely determined by the size of the understock. In some cases, a graft may be made to join a scion and understock of nearly equal size. The other type attaches a small scion to a much larger understock. In this case, several scions may be attached to the understock as in cleft or bark grafting.
Materials needed:
- Knife
- Grafting wax - After the graft is made, some covering must be used to keep it from drying out.
- Grafting tape - A special tape with a cloth backing that decomposes before girdling can occur. Tapes may be used for binding grafts where there is not enough natural pressure. Electrical and masking tapes are also
- Budding strips are elastic bands. They look like a wide rubber band that has been cut open.
- Nails - Veneer, bridge and inarching grafts require long, thin nails.
- Grafting tool- a blade used to split the stub and a wedge to hold the split open while the scions are inserted.

Grafting Method From Wikipedia: Approach grafting or inarching is used to join plants that are otherwise difficult to join. The plants are grown close together, and then joined so that each plant has roots below and growth above the point of union. Both scion and stock retain their respective parents that may or may not be removed after joining. Also used in pleaching. The graft can be successfully accomplished any time of year.
