Time to graft

 


The trees may be grafted any time in the spring before the sap begins to flow. It is generally performed about the time the trees are pruned in the spring. If the trees are not grafted at this time and the scions are kept dormant in some cool place, such as an ice house, the grafting may be successfully done later in the spring when the cutting will not result in serious bleeding.

The most important factor in top-working large trees is the selection of the branches to form the top. Scions when grafted on horizontal branches, instead of continuing to grow in the direction of the original branch, always grow upward. This tends to produce a narrow, high-topped tree. Great care should be exercised, therefore, in selecting branches well away from the trunk and covering all the fruit-bearing surface of the tree. Scions seem to grow more successfully on branches which do not exceed 112 inches in diameter at the point of grafting. In top-working an old tree, about a third of the branches that are to be grafted should be worked each year, as the cutting of more in a single season would prove injurious to the tree. It will therefore take from three to five years to renew the entire top. Where the fruit-bearing surface is large, this will often necessitate the making of from 10 to 20 grafts each season for three successive years. All the important branches should be grafted, and it is safer to graft too many branches and be obliged to cut out a few in later. years than not to graft enough.
