Zelkova serrata

so everything happens/begins at the top edge of the cut collar...
(unless, as you said, you are working with a cascade    )

thanks !

Thanks for the help. I already put a tourniquet around the trunk and buried it. If it doesn't look like it is starting to swell come October when I dig it up, I will cut another ring, apply alcohol, cut the diagonal strips 1 cm long as was suggested, add another wire around the top of the ring, and bury again.

This about covers it all...  

Thanks again.

I'll take that as a "no" then.

Hi

Here's a pic of the cut, and with the wire under the flaps to flare them.



This method is well worthwhile on thicker branches, and for all air-layer cuts don't be scared to go into the wood a bit.

Thanks again. I'll try that.
