Multiple trunk river birch (Betula nigra)

[noob72]

I recently read an article about splitting single trunk to make it a multitrunk tree. I have a river birch, and they seem to make good specimens for the split trunk style. The tree is a field grown river birch that has a 3 inch diameter trunk, and I'm considering splitting the trunk in 2 or 3 when I do the trunk chop. It is my assumption that I will need to wedge something in the splt(s) to keep them from fusing back together. Anyone have experience or advice for splitting a tree at the same time as trunk chop? Would a better option be to cut the trunk lower and keep 2 or 3 leaders to achieve the split effect. I'm thinking if I do second option the trunk would have to be cut pretty low to give the split a more drastic appearance instead of a slightly taller trunk that will give me a straight single trunk before splitting at the multiple saved leaders. If you recommend second option, how low would you chop? If you recommend first option, should I let the trunk get thicker before chopping and splitting?

Thanks for any insight.

I’ve seen this done on the nebari in several different methods. Can you share the article?

Not one I saved, and I can't seem to locate it in my history.

Be aware that Birch are soft wood that rots easily. I have found the one I have sends out low sprouts easily when chopping the trunk. Try that first maybe?
