Elm Thread Graft question

[sorce]

That info about not scratching em may have been maple specific....

I can see different trees acting differently.
Seems I can put 2 ficus pieces close to each other and they'll fuse. I feel it working. I don't feel that elm working. Something about the hairs on it.

Horticulturally, it's as simple as one healed before the other, or, the hole healed before any connection was made, so you wood have had to wait another season of laying down those connecting pipes to make it work, and I don't think it's garaunteed still.

Scratching it afterward, like we reopen a wound, can help establish those pipes I reckon. Worth a try next time.

I'd be looking at doing something with those funky roots before I worried about branching.

I would assume it cant hurt.
Would you scratch the entire scion or just where the cambium and scion touch?

funky roots

HAHAHA you don't like my above the soil line root trunk?
I kinda like the exposed root thing... but I weird...
Got this tree that way... not much of the tree left if I messed with the root trunk.
It's not really one of my pride and joy trees. Fun to mess with though.

I'd try and scratch it for both sides.

This is when the toothpick, or better, another branch gets used to but them together before you seal it up.

This may be Peter Tea Blog stuff.

Interesting... thanks for sharing.
Wish there were pics of the process... the author said that Peter recommended scoring the top and bottom... guess its the same a scratching just to open up the scion.

I've had a Japanese maple thread graft get me all excited only to see it fail. My lesson is if it grows and thickens so much that wind or its mere weight could cause stress at the union point, then shorten it.
