Hi... Wondering if any of you can assist.

I have a large Premna Japonica. It has a 6 -7inch base. Just above the base low down on the trunk it has 2 ver large branches which I was wanting to remove. I want to air layer them and then chop them back as close to the main trunk as possible. Is it possible to air layer and chop back unwanted branches in the same season or should I air layer first. 0r give the tree time to recover. Then remove/chop each large large branch one at a time(one each season after the last)

Hope this doesn't sound to confusing...

All replies welcome

When taking airlayers, the speed of root formation depends in part of the amount of foliage that is 'above' the layer location. So I normally leave all the branches on the plant. Start the layering process. When roots have formed in a sufficient amount, I do mayor trimming, leave the plant for a few days so the open wounds can seal, en the plant can restore moisture in the layer. Then I trim the layer off and pot them up.

Make sure all cambium is removed from the layer-location. Otherwise the branch will heal the area. Effective way to do this is to leave the layer exposed to the dry air for a bit (10mins?). This way the wound dries out, and the cambium cells die off.
