I've had great success performing layers in spring, either just before the spring push or after the leaves have hardened. I've never layered something this late in the year, but I've always thought about trying, since trees tend to grow a lot of roots in the summer and fall....so I made one today, using my knob cutters and the evil rooting medium of moist sphagnum moss. It is 90F today and humid as hell...my first frost date is typically in early November but can come as early as mid to late October. Let's see what happens.
