I done a few trees this passed Spring they all took ,J Maples, Spruce , Fringe flower, and this pine. I potted it in a mix of Akadama, Pumice and Lava Rock hoping for the best.

How long did it take until you could cut it off from the main tree?

I done the air layer in Sept 24 (2020) and removed it last weekend 27/3 you can count on six months, I could have removed it in Feb but because we are going into winter by me, wanted as much roots as possible.
