Thread grafting Hawthorn roots
« on: May 21, 2012, 11:45 PM »
Hey there, I've got a hawthorn tree that I've spent the last couple years rehabbing and I've finally got it looking really healthy. It's a pretty tall tree, with decent branch structure, old bark and I really like the look of it with one exception. When I got it it had some pretty gnarly aerial roots. I've thought about doing an approach graft with them but think it will still look kind of bad. The second option was doing an air or ground layer above the highest root, but this will shorten the tree by at least 4". I'm not sure I want to lose that height.

So I think I'm down to two options, simply cut off the offending roots and maybe do some ground layering where I'd like to have more roots, or cut off the roots, clean off the bark and try thread grafting them into the base of the tree right at ground level. I've seen people do thread grafts before with maple saplings, but don't know if you can do it with just roots. Is this possible, or do you need to have a whole tree that you are threading through the trunk? Any help or tips would be much appreciated :)

I think that the idea behind the thread graft is part being threaded needs to grow in diameter causing the cambium layers to fuse. Not sure how the root section would respond once cut from the trunk and threaded.

Might have a nicer tree in the long run by layering and developing the nebari that way.

I've gotten this notice before and I'm still confused. You say to upload "here" but I don't know what here you are referring to. I'm not trying to be arbitrary, just confused.

By upload, we mean that you click "Attach" when posting and browse for the picture on your computer.  When you click "Post" it uploads the file from your computer to our server and we host the image.

The alternative, and what usually sparks this notice, is to post a link to some other server/service that hosts the image.  That is less appealing to us because often those images get moved or removed and we're left with a thread that is much less useful than it used to be.

tried doing it that way, it timed out and didn't work, then when I tried again it failed and said the post could not be saved, fun times.

If you're trying super huge files just try one at a time. It's likely timing out while uploading.  Otherwise shrink them before upload.
