I've never tried to air layer this variety. Is it easy? Have you got any advice?
Thank you!
It seemed to be about the same as layering most of the other cultivars that I’ve tried. The roots looked a little unusual compared with other maples’ roots, but they grew with similar vigor.
I did this layer by girdling the trunk with a grafting knife, removing a ring of bark, scraping off the cambium layer underneath, and wrapping tightly in moist sphagnum moss. I poked some drainage holes through the plastic bag covering the sphagnum, so excess water could drain out the bottom. I also left a bit of an opening at the top so I could water the layer.
