Need Advice on Black olive tree

Repotter

Equally important to doing it at the right time of year is making sure you follow the right technique. Make sure the ring of bark you remove is wide enough to not allow the growth to "bridge" the gap.
The usual accepted width of bark to remove is 1 1/2 times the diameter of the branch or trunk you are wanting to layer.
Procedure is once the bark is removed down to the woody stem then treat the wound with rooting hormone.
I wrap this area with wet sphagnum moss and tie with twine.
I then place a split plastic pot around the section and tape it with a water proof tape to hold it in place. The pot should only be split on one side and a hole cut into its bottom large enough to accept the diameter of branch being airlayered.
I use aged pine bark to fill the pot once secured in place, then keep it damp until the roots grow sufficiently to be removed.
Approx. 6 to 8 weeks the roots will fill the pot. It can then be removed by cutting from the main branch or trunk and potted in its own training pot to grow on.

Good luck, keep us informed on how it goes,...Hector
