Tongue grafting

• This is the modification of whip grafting • In this method, a slanting cut to whip grafting is prepared on root stock and scion
• A second cut is also given in reverse direction on previous cut in root stock and scion
• The second cut is started downward at about one third distance from tip and should continue to about 1⁄2 the length of first cut
• The scion and stock are inserted which interlock each other • After uniting rootstock and scion, both are fastened using polythene tape
• This method secures contact with six layers of wood hence chances of union increases and there is quick healing in grafting
• This method is used for propagating apple, pear and walnut
