Welcome Aboard Bonsai Nut!!! That’s a good start on these trees!
Maple design is generally falls in two patterns
”Design by a thousand small cuts”. Whereby the entire tree is basically clip and grow. This method can produce artful, delicate designs.
“Design by a 800 small cuts and some big ones too.” This procedure is similar but also features the use of successive sacrifices on apex’s to foster trunk caliber and chops.
One caution. In every case be sure to cut a bit off the actual cut site each time, between internodes, then let the section die off vs cut smooth against the trunk. Cuts heal better and this procedure will help avoid infection of the trunk.
Finally please enter your approximate location and USDA plant hardiness zone by clicking on your icon atop the page, then account details and scroll until you see these areas. Enter and save.
This information will help us help you in the future.
