This past spring I took some new growth cuttings from some Japanese mountain maples. I had about an 80% success rate with the following method - Just after the leaves hardened off took cutting and stripped bark on bottom 1" with at least 1 node, dipped in root tone placed in 1/2 turface and 1/2 vermiculite, placed under 24 hour flourcent light indoors, covered with clear plastic container, misted and kept soil moist. In about 90 days they had rooted and are now growing well outside.
My question - is there a reliable way to take thicker cuttings (1/4 -1/2")? I have read that you can take them in late fall and they will root over the winter outdoors. I have a larger maountain maple in a container which I will be chopping in spring and wanted to get all starters I could off of it before the cut.
