Hello everyone, I tried to airlayer three branches of a young zelkova tree in early August. I realized it was a little late in the year, but the tree was cheap and I wanted to give it a try. I pealed the bark on all three branches (which are all about as thick as a little finger), powdered with rooting hormone and wrapped in moist spagnum moss. All three branches developed lots of callus, one branch had lots of roots on one side. I cut off all three branches and potted them although two of the three had plenty callus but no roots. All the leaves are dropped at this point anyways, so not much would happen with them from here on. My question is: will the branches continue to develop at leasta few roots while the weather is still mild and the soil somewhat warm? What can I do to encourage them to send out roots from the callus and start grwoing come spring? I figured they wouldn't have a chance if left on the tree as they would freeze solid in the winter. Does anybody have experienced a similar scenario? Thanks in advance for your thoughts and suggestions.
