I currently have quite a few Maples, Japanese and Trident, and I was hoping to get some help on two of them specifically.
As you can see, they're both very long to thicken the trunks and roots, and as they're nearing the point where I'm happy with the thicknessI am keen to take the design process to the next point.
What is the best course of action to get both a Japanese maple and a Trident maple to back bud on the trunk? I’m very cautious/scared to do any sort of trunk chopping especially since the roots have nicely grabbed the rocks they are planted over after a few years and I would hate to kill the trees after waiting so long. I know you can't dictate where buds are going to pop exactly, but I'm hoping to get SOMETHING a significant amount closer to where the bases are now. The Japanese maple was grown from a seedling and I'm very attached to it.
Any information about the best process as well as time of year would be greatly appreciate, or potentially a link to a very in depth and informative video would also be wonderful. I currently reside in North Birsbane to give an idea of the climate.
