Uprooting field maple

This maple didn’t do a lot this year. I hope August can give it a bit of a power up. Please note that I had to put a rock into the pot to prevent the wind from bending to hard on the raised roots. Don’t think it is very endangered but it doesn’t hurt other than looking a bit odd.

Reagrding the uprooting part, this plant sits in a deep pot and it might have rooted far down, but I don’t know. I also wonder how to tackle the uproot in detail, do I raise it each year a bit more or do I wait for the roots to thicken up and raise it further in one go? Another thought is that this tree could stabilize when I’d cut it further down towards the point of uprooting. The whole process confuses me, so if you got experience I’d be happy to hear from your experience.

Looks like I need to do some more research on how uprootings actually work and what’s the time horizon until the roots above surface can carry the tree.

In the bonsai magazine (Bonsai Art) that I read from time to time I saw that there is a technique where root’s are exposed to a very long extend, even so far that the roots make the actual stem. I like this type of bonsai style so I wanted to try it with an acer campestre that I got from a friend (along with the walnut tree). I tried to wire the root together somehow in the hope that they will fuse. I keep the small tree in the cellar for overwintering and maybe next spring I will cut it back hard, depending on where the buds appear.
