I've read the Red Maple (Acer rubrum) does not reduces leaves or internodes well. So if you were to make a bonsai out of one, you should go big, to fit the proper scale. I think I found a good sized base to build from!

This tree was in the woods behind my house (on my property) and tipped over in 2016. I cut it off leaving a stump and planned on just removing the stump eventually. Last year it sprouted back pretty well and seemed pretty healthy aside from the deer constantly removing the growing tips and foliage. Once I realized that I could potentially use it as a bonsai, I went full-weirdo and put up driveway marking stakes around it and tied fishing line between them to protect the foliage. This April, as it was budding out, I dug it up and potted it.

As it was in the ground:

I expected it to have a very large root ball, so I dug a large trench around it.

It turns out the roots were quite flat and only had two roots running straight down into the dirt. I popped it out with very little effort. Unfortunately, there were almost no feeder roots in sight, so I hoped for the best.

I cut the roots back just enough to fit in the largest grown box I could find/build, a ~30"X30" (76X76 cm) pallet, and potted it in 80% perlite, 10% DE, and 10% bark. I placed it off the ground in mostly shade (away from the deer path) and crossed my fingers.

As it stands today.

I'm cautiously optimistic, hoping it likes it's soil and putting out lots of roots.

Yeah the maples are funny. They tend to put out a lot of roots. I collected a beaten up cut leaf read japenese maple from my backyard as well. It’s doing well, but I need to cut it back at some point. I wasn’t sure of the health of the tree so I didn’t cut it back right away. When do you guys think I should cut it back? It’s about 18 inches tall.

I don't have a ton of experience with collecting material, but I think the easy, short answer is: when you ARE sure of its health. I would give it at least a full growing season before cutting anything back. I also don't have any experience with japanese maples, so I won't try to guess at when to chop it.

I like it!

I would have probably cut back some of those big roots more. They are really not going to do a lot for you and will need to be cut back in the future. It would have certainly made it lighter.

@jeanluc83 I was definitely considering it, but a couple of the big roots had some little feeder roots near where I cut. And since it had been constantly trimmed back by deer last year, and lived in full shade, it is probably running low on stored energy. I wanted to keep as much of the large roots as possible to maximize the amount of stored sugars and nutrients. Probably playing it too safe, but I can always cut back later if it lives.

For future reference, you did not collect any feeder roots with this tree. You collected hardened off fibrous roots that do not absorb moisture. The tree has to produce the feeders as it recovers. Fortunately, this is what happens most of the time.

You left the radial roots waaaaay too long. This will force you to do a second root chop down the road. Your feeder roots will emerge mostly from the cut ends of the large roots, so you'll lose them when you reduce the root mass.

Finally, you can expect this large red maple to start rotting from the trunk chop point in about three years. With management you can end up with a cool looking specomen, however. I've seen some fine examples.

@Zach Smith Bummer about the roots. Oh well, live and learn, and thank for the info. There is about two or three inches of wood above the top-most branch that I can cut back/carve once the tree recovers and start treating it immediately to prevent rot. However, there is a hole in the base that looks cool, but will likely cause rot from the bottom that I will have a difficult time controlling. So it is definitely a concern. Thanks for the head's up!

If you ever discover a treatment for a red maple trunk chop that prevents rot, please let me know. This one has stumped me for decades.

Looks like a fun project. Really let everything run long both to help generate roots and to minimize dieback to the extent that it is possible. Even with significant amounts of rot, you are going to have a lot of material left to work with. Keep us updated.
