Hi,

I have three air layers (branch calipers between 3/8 and 3/4") started in April on a large Sango Kaku Japanese Maple in my yard. The top sections above the layering point on all three are doing well with lots of new growth. I used the split pot method with bonsai soil, so I can't see the root development but I'm pretty sure it's moving along also. I want to leave the connection as long as possible, but I need to separate the layers before the Winter because I'm moving. Does anyone know whether it would be better to separate in late August before leaf drop or after the leaves fall. I plan on leaving them in the pots they rooted in, in a cold(35o) house until spring, how should I treat the cut end? Wound sealant? Maybe partially bury the whole small pot in a larger pot with fast draining soil and allow the cut end access to moisture? Any help is appreciated

Thanks,

Steve
