For cases where the diameter of the scion is bigger than the diameter of the rootstock, I like to use the Z graft. Had the scions been significantly smaller than my target branch, I would have chosen the bark graft instead. For this particular graft, the scions that I received from the CCPP were slightly smaller in diameter than my target branch, so I decided to use the cleft graft and I selected the scion closest in size to my target branch. Scion grafts on the other hand are more likely to grow and they grow more quickly. I have found that chip bud grafts and T-bud grafts of additional citrus varieties tend to be very slow to grow or they do not grow at all. There is no single best grafting method for citrus, but when grafting multiple varieties to a mature citrus tree I often prefer to use a scion graft rather than a bud graft. To learn more about disinfecting grafting tools, please see the following link: Disinfecting Grafting Tools.Ĭhoosing the Grafting Technique based upon the Scion Size In order to both maximize the probability that the graft lives and also to prevent the spread of disease from tree to tree, it is important to disinfect grafting tools between grafts. The below YouTube video goes through in detail the process of setting up an account and placing a budwood order with CCPP.ĭisinfecting Grafting Tools Disinfecting grafting tools. Here I have created a web page that lists some other programs: Citrus Budwood Programs. Many citrus growing regions where CCPP budwood is not allowed have their own disease-free citrus budwood programs. The CCPP will ship budwood anywhere in the world where the local government allows it. We now instead order our budwood at a nominal cost from the Citrus Clonal Protection Program (CCPP), a program that exists to provide disease-free budwood for the grafting of citrus trees. To save our trees from deadly diseases, hobbyists in California no longer swap citrus cuttings with friends. The situation is so severe that it now against the law in California to graft with cuttings taken from backyard citrus trees. In California we now have both exotic diseases that kill citrus trees and also the insects that spread the diseases. This makes the source of citrus budwood for grafting very important. It is often not apparent when a tree is infected with a fatal disease. In addition to this step-by-step guide, I have also made a YouTube video (see below) showing the cleft grafting of citrus trees.Ĭitrus Budwood from a Disease-free SourceĬitrus cuttings have the potential to spread tree-killing diseases. Grafting Citrus Trees with the Cleft Graft – YouTube Video Although this tutorial shows the use of the cleft graft to graft a new variety to a mature citrus tree to make a multi-grafted citrus cocktail tree, the cleft graft is also useful for grafting new citrus trees. Although this tutorial shows the use of the cleft graft to add a new variety to a multi-grafted citrus cocktail tree, the cleft graft is also useful for grafting new citrus trees. In addition to citrus trees, the cleft graft is also useful for grafting fruit trees of many other types. The cleft graft is useful for grafting citrus trees of any kind including: oranges, mandarins, lemons, limes, grapefruit, pummelos, and kumquats.
