Propagating by cuttings is ENTIRELY about energy, energy within the parent tree and energy in the cutting. Plus the associated hormonal levels in the cutting tissue. Nearly all broadleaf evergreen shrubs and trees, CITRUS INCLUDED, root best from late August to middle of November. This is because at that time of year the energy in the cutting is at its highest. Most of the cuttings will be rooted in 5 to 8 weeks. In general, it has been found that there is no ideal rooting medium, but several combinations of materials can provide a good, workable medium with a drainable pore space of 40 to 50 percent. Good quality peat and coarse perlite, or peat and ground pine bark on a 1:1 or 1:2 basis by volume works well in propagation containers approximately 3-1/2 to 4 inches deep. Be sure not to push the bud stick down so deep into the container that it is in the saturated mix, which is at the bottom of any container. The incorporation of Osmocote 18-6-12 into the rooting medium prior to the sticking of the cutting greatly increases plant quality. With Osmocote, stimulation of rooting is substantial on some broadleaf cuttings, while others are not affected during rooting, but growth of all liners before and after transplanting is always greatly increased.
