I was wondering if this would work.

Two years later, still wondering. Just look at the little buggers go, just starting to bulge around the plastic now. I'll update again in fifty years or so.

Another factor that you must take account of is species - Quince do not fatten very quickly at all. It may take longer to fuse than the plastic has in terms of maintaining a viable structure - even plastic breaks down and gets brittle over time.

Quince was the only available plant I had to try with, I'd like to see someone give it a shot with tridents or something.

When this is the normal plastic, is will first stretch before it will cut in. The result in my experiment was a one-sided rootsystem.

Normal plastic.. Not sure I think it's polyethylene which is more rigid and doesn't make scale foliage as compared to polypropylene which is softer and needlyer but I might have that backwards and it might have been mislabeled too so its hard to say for sure.

Seriously though it's pretty stiff stuff and I think it may actually work especially with a tree species more suited. Thanks though for sharing!

Lolololololol!

I kind of did the same on my Tilia but I used wire that was tighten around the area where I want the roots to grow. I'm looking to start new roots all at the same height. Not so much concerned about them being flat at the moment. I read about this layering method on bonsai4me.
