What is this tree I've twisted up?

Been abusing this tree for about three and a half years now as my very first project, and I don't really know what it is. An Aspen or Birch maybe..? Can anyone help identify it so I might zero in on proper care for it?

Yeah looks like a Populus to me, if it was in my area I would guess Populus deltoides. I get a lot of volunteers in my pots and one I'm letting grow along with a tremuloides volunteer. My cottonwood has giant leaves right now.

Thanks.
Mine just showed up in one of my pots too.
Yeah the pictures I put up are about a month old and I had just cut it back and defoliated, which I learned was a mistake because I guess trees go dormant in June, lol.
The new growth since then is pretty exciting to see though, very encouraging.

Have you done any work on yours at all?
 
Not a lot, just some pruning to control growth, no wiring. Removed a really dominant shoot a week or so ago:

Just building a trunk, not sure how well I'll be able to tame the leaf size, although yours looks pretty good (could be a different species still not certain). My quaking aspen has much smaller leaves and internodes but this one is growing very vigorously, I have not disturbed the roots on this one since it sprouted in this pot of potting soil. I did dump a ton of osmocote plus in the pot so that might be why I'm getting the growth I'm getting.

Your leaves ARE huge, lol. I like the trunk shape. When I started this one I was afraid to cut the trunk when it was small, probly a mistake but oh well... first tree.

I've done several cutbacks and defoliation which does seem to have an effect on the leaf size. Been giving mine just a little fertilizer until just yesterday, went with full strength. The leaves may get bigger, I dunno.

Picture of the new growth. I guess Bonsai artists don't use inosculation like I have either, another rookie mistake. lol

I want to see if this inosculation thing works, but when I take the wires off...

Do you think it would be better to chop the trunk and work on it in a similar way to yours? ...or keep the fused branches and maintain it's size?

I know no one wants to be rude, but I think I need an experienced opinion. :)
 
I was browsing some threads and @MaciekA has some expertise with black cottonwoods and might be able to help you out better. Not a lot of people working seriously with this genus as bonsai as far as I can tell.

OK Thanks.
No opinion on the branch fusing? It's OK, you won't hurt my feelings. lol

It could work but I think an approach graft would be a better technique to get the result you're after, I assume you just bound the branches together tightly?

Comparing your first pic to your last set I would be concerned that the leaves are showing some chlorosis.

Oooh.. good, thanks. That's helpful.

Yes, I just bound them together to see if I could fuse them.
 
I’m on mobile right now so I could be wrong but it could also be populus nigra which is widely planted in the US and can get around on its own. I started a bucket of populus nigra cuttings a few weeks ago so the species is on my mind lately.
 
Also, poplars and cottonwoods don’t really have trouble creating branches in low places — unusual techniques not really necessary.

If I could give some advice, I’d undo all wiring/wrapping/etc, fertilize well this year (no pruning or anything else), then bare root into a more appropriate media just before bud push next spring.

Then come back to this thread and talk about the thing all populus growers need to know about when in the early strong growth / repotting / bare rooting years: Preventing sucker growth from causing issues and dieback. Master that and poplar/cottonwood become very well behaved trees that respond to deciduous techniques well, including defoliation.

Thank you, yes...
Because of what I learned from Empty Mountain, I've already unwrapped the branches and removed the decaying branch ends that I couldn't see.
And I just fertilized it.

Now I suppose it's just a matter of waiting until next spring. :)
 
I really appreciate the insight I'm being given, thank you all. This is good. :)

See if you can find more of this species -- when I started out with cottonwood, having a couple of them on the go in parallel really helped me tease out the behavior and figure out what's normal (timing, responses to techniques, etc).

There might be a few I can dig up. Sounds like a great idea.
