Shield budding (T budding) and chip budding.
(
a
) The technique of shield budding: (A) The bud nearest to the upper
end of the budstick is removed by a shallow slicing cut. (B) The stock
is prepared by making a T-shaped incision (D) through the rind down
to the wood. The rind (E) is lifted and the bud inserted (F). The tail or
handle (H) is cut off at the horizontal incision and the bud firmly tied.
After Garner (1988). Reproduced with permission of Mrs I.L. Garner.
(
b
) The technique of chip budding. (A) The first cut is made
downwards in the side of the stock. (B) A second cut,20-55 mm long
is made downwards to meet the first. (C) A bud chip is taken from the
scion bud stick by making a horizontal cut 12 mm below the bud and
a second cut starting 25 mm above the bud to join the first. This bud
chip (C) is then fitted to the prepared stock (D) and temporarily held
by the stock flap (E). The cambia of stock and scion should be
matched,which usually leaves a layer of the outer rind of the stock
visible (F). The bud is then very firmly tied and sealed in place. After
