Larch Air Layer

I air layered a Larch, now it has roots, it is the beginning of September, when is it safe to separate them? I am concerned with it bleeding, or is late summer a dormant time for a deciduous conifer? If I wait til winter it is too cold out for the roots to start growing. If I do it in the Spring I think it will bleed for sure. I live on Vancouver Island in BC, Canada. Someone from the UK said to do it now. HELP!


Hi Darlene, I would wait until late February now. As the green just starts to show will be the best time to separate. As for bleeding, all larch bleed when they’re pruned, no matter what time of the year.


Thanks Keith, that is what I am going to do, wait till the green starts to show, which is the best repotting time. Yesterday I unwrapped the covering and found lots of roots, I then cut a one gallon pot and placed it around the air layer, tapped it closed and filled it with fish bark mulch and pumice. I think this way it will feed the new roots, encourage some growth and then protect it when the winter months come.

With the amount of roots i think you’re pretty sure to be successful.
