Multi air-layer Japanese maple

[Ravaginggoatman]

Today I harvested the three air-layers that I started earlier this spring. Fortunately all layers rooted successfully. This maple was in our yard and needed to be taken out, so I potted up the tree last fall. I am wondering with so fewer roots should I remove more foliage or will the roots provide enough water to sustain the tree. Any advise would be appreciated. Also what are your thoughts going on base of the tree (large slug looking root).

Well done!.

Layers seem to survive with remarkably few roots. I guess separating them is a real incentive to grow some more new roots. If you've underestimated the roots the tree will usually just shed some a few more leaves until it reaches current root/leaf balance and then continue to open new leaves as the roots extend.
Just make sure it does not get dry for a few weeks. Keeping the foliage protected and shaded and occasional misting a-la cuttings will also help it get past the sudden reduction in roots.

Agree with shibui assessment. I think if layers are happy you will see new buds opening and nee leaves in 1-2 weeks.
And you can still layer the base as well. Plenty of time, although not much foliage above to support creation of the new roots.

Thank you for your suggestion. I have them under a large 50% shade cloth awning (summers here can be brutal) 107 next week. I hadn't considered misting but will definitely do that and make sure that they don't dry out.
