A. palmatum dissectum air layer

[PiñonJ]

I’ve read once, or twice on B-nut that dissecta are very difficult to air layer, but my landscape maple is throwing an apex outside of the desired silhouette, so I’m giving it a shot. I’m letting the girdle dry out for a couple of days and I’m trying to decide whether to go back and angle the upper cut to the desired planting angle, or leave it as is, because I cut it right at a node. @0soyoung , you mentioned on the science of air layering thread that roots should emerge more easily at a node. Given these cultivars’ difficult reputation, do you have an opinion on whether it makes enough of a difference to leave it as is?

I would leave it as is. Make sure your top cut is clean - like cut with a razor blade. (It doesn't look very clean in your photo). Then apply a rooting hormone (or not) and make sure you media is packed tightly and securely against the top of the girdle. The rest is time and luck.

make sure you media is packed tightly

I’ll use sphagnum and I’ll certainly pack it in, but if it’s too tight, won’t it exclude air (and therefore oxygen), not to mention creating a physical barrier to root growth? I guess I should ask you define “tight” and whether it’s a recommendation specific to maples.

I would describe it as calvin klein boxers. Tight and confortable but not impeding circulation.

Good luck, I have not been successful doing a weeping. Seiryu is an upright and will easily airlayer.

Good to know i wanted to airlayer my seiryu

Emerald lace cultivar will layer too it is also an upright dissectum, wonder if there is a link between how weeping they are and how well they layer
