So Elm can be grown from roots. I haven't grown any from roots about as small as pencils before, but I guess I can try today. I used roots you see removed from the trunk that were long. You can see what I'm talking about from the first full sized image in the first post.
Here's a shot with the two seedlings and 5 root cutting attempts threaded where the gaps were. Red arrows are the seedlings. Green arrows are 3 of 5 root cuttings. Blue arrow just points to something that the thing I used to secure the top of the roots keeping them exposed to light. Hopefully the root cuttings grow, and I'll have success in a year or two getting an improved root spread.
Don't mind the small wooden board. I used whatever scrap wood I can get.
Back into the pot, chopsticked to fill dirt in between the roots, and watered. Here's the shorter tree with all it's rootwork done for the year. Yay!
