History
ancient technique

Grafting
two different plants are
united so they grow
together as one
Scion - top - vegetative
part
Stock - bottom - root part
Reasons for use

disease resistant roots
cause dwarfing
top working - grafting
many different varieties to
the limbs of one tree
Reasons for use
insert different variety for
cross pollination
propagate plants difficult
to bud

other to enable the stock
and scion to grow together
Requirements

vigorous growth
Requirements
Timing
