Air Layering Larch

I’m wondering if it is possible to air-layer a Japanese Larch ? If so when is the best time to do so.
Any suggestions that would help would be appreciated.

I’d guess it would work, and I’d expect now is a good time to start it, but I have no experience layering larch. If it’s a nice tree you’re working with, I’d want to find some evidence of it working before getting started!

I have never air layered a Japanese larch. When you posed the question, I checked my written resources and conducted an internet search. The best I could find was the comment that it was possible but difficult. No actual accounts of success or photos showing a preferred process!
Based on that I would only attempt it on younger, less valuable material. Also I would choose a slower approach to give the tree more of an opportunity for a successful outcome. Thus I would use the traditional tourniquet method that allows the tree to slowly swell and cut off the cambium rather than ring bark the tree! I would expect the best results to be over a period of two growing seasons if it works!
And out of an abundance of caution I would protect the tree over winter to avoid damage to new roots if any occur during the first growing season.
Just thoughts from previous attempts on difficult material.

Thank you Gentlemen, I appreciate your input.

Yes it does work and we tried this as a bonsai demo at our local club and the tree rooted well within 10 weeks! We removed a 1inch strip of bark/cambium, with a stanley knife, dusted the upper cut edge with hormone rooting powder then wrapped in damp sphagnum moss and covvered in cling film , followed by an outer cover of black polythene.
Hope it works for you- sorry no photos !


Thanks Alex, I’ll give it a go.
