Hey there! My understanding of bud grafting is that it is
grafting with a single eye or bud. Normally performed at the height
of the growing season by inserting a dormant bud into a shallow
slice under the rind of the tree. The bud is sealed from drying and
bound in place. There are many styles of budding depending on the
cutting and fitting methods, the most popular being shield budding.
Other budding styles include the inverted T, patch budding, double
shield, flute budding and chip budding.
