Which Place Can Be Choose To Put The Graft?
In choosing the place to put the graft use an upright-growing limb preferably less than two inches thick; grafts on larger limbs are almost sure to he blown off when they grow to big size. The graft should not be heavily shaded because it is like a plant and needs light to grow.
On the other hand, a stock of large size needs some shade to protect it from being burned and killed by the sun. This is because the thick limbs of a tree are not equipped to resist the sun; they depend on the shade of the overhead branches and when this is removed in preparing for the graft, they are in danger. A leafy branch should be bent over such stocks to protect them till the grafts start.
Saw the limb at a place where a long straight split can be made. In splitting large stocks keep in mind that these stocks arc likely to close too hard on a cion and crush and kill it. To avoid this make the split extra deep so that when the jaws close the pressure will be just enough to hold the cions.
The thickness of the cion is often given as a quarter inch. I think that is too thick because it opens the deft too wide and makes too long a split necessary; if thick cions are used the part that is to be inserted should be thinned to three-sixteenths.
Notice that the end of the cion is cut with a slant that points downward to the thick side; this is an indicator that speeds the work when making the insertions. I take the dons into the tree in a small can of water attached to my belt; most grafters use them dry. Some grafters tilt the clans in order to make sure that cambium meets cambium. Cardinell and Bradford of the Michigan station concluded after microscopic studies that there is more assurance of good contact if the cions are upright. Too much care cannot be used in making smooth cuts on both stock and cion.
