Trident Maple Root Grafting Question
« on: July 13, 2011, 06:31 PM »
I've got these two tridents with unappealing roots. (The straight trunks are another issue.) I am interested in trying to graft new roots on these right around the spot where they begin to flare outward, and then over time I'd be able to just chop off all those that are going straight downward and keep the new horizontal roots.

My question is which grafting method is best. I saw the very helpful post in this sub-forum about approach grafting. But I suppose another option would be what some refer to as the tourniquet method, tightly wrapping wire around the trunk to produce flare and new roots just above the cut point. I suppose yet another option would be to air layer, which possibly could overcome the straight trunk dilemma.

Which one would you do with these trees? Is one faster? Is one more risky? Open to suggestions.

Thanks.

For maples, I have always used thread grafting.  slowly drill a hole where you want new roots and slide a seedling/cutting through the hole.  I think it has taken a full growing season for the grafts to take before they are removed.  I suppose this technique is limiting in the fact that it requires younger material, but it is excellent cause you get results much faster AND you decide exactly where the roots go.  Ground layering(tourniquet method) doesnt always work, and you certainly dont get to choose exactly where the roots go.

Can you expound on what you mean by limiting, and the requirement that plants be young? Do you mean the material being grafted onto the main plant should be young, or that the main plant must be young in order for the graft to take hold?

I would try potting the tree deeper in the pot.  Make a growing box allowing the roots to spread out and see if you can get a wider base and more taper to the trunk by allowing the apex to grow straight up.  You can cut the apex back later.

I think a ground layer would give a much better and faster base development than grafting. Grafting is good if there are only a few spots that need filling. Here's a quick vert for an idea.

I would air layer this tree up the trunk at the spot where you have some inverse taper. You'll end up with a much better tree.

As far as root grafting goes I've had good success with approach grafting. I use 1-2 year old whips and cut a vertical croove with a dremel at he graft site the same diameter as the whip, scrape the sides of the whip down to the cambium where it will contact the sides of the groove, and nail the whip into the groove with a small brad or finish nail. Seal with cut paste and you're done. Close to 100% success rate!

I used the word "limiting" with the thought that most people probably do not have young cuttings or seedlings laying around to use as grafting material.
