In this video on growing citrus from cuttings, I show how to root citrus rootstocks in stonewool. These rootstocks can then be used to graft citrus trees of many different varieties. For example, to propagate a lemon tree, rather than rooting lemon cuttings, citrus rootstock cuttings are rooted. A lemon cutting is then grafted to the rootstock. Grafting to a rootstock will produce a superior tree. Benefits include disease resistance and improved fruit flavor and texture.

Materials that I used to root the citrus rootstocks in stonewool can be found here:

When propagating citrus trees from cuttings in California, it is mandated by state law and regulation that cuttings come from a registered source. This is to avoid the spread of the deadly huanglongbing disease that is now spreading. Disease-free cuttings of rootstocks, lemons, limes, and other citrus varieties can be ordered here:

Once the rootstocks have been successfully rooted, please see the following videos that show how to graft citrus trees:

In California, the collection of any citrus propagative materials, including budwood and seeds, from non-registered sources is illegal. Any citrus trees grown or grafted in California must come from source trees registered with either:
(1) The Citrus Nursery Stock Pest Cleanliness Program, administered by the California Department of Food and Agriculture, or
(2) The Citrus Clonal Protection Program, located at the University of California at Riverside.
