Dwarf Japanese Maple - Crack where branch meets trunk.

peterw99November 10, 2012

Hello. I just noticed that my Dwarf Japanese Maple has a substantial crack in one of the main branches where it meets the trunk. I've attached a photo, and was hoping that some wonderful tree loving soul could offer some advice on how I can save this branch that amounts to 1/3 of the tree. If I lose this branch, the tree would be irreparably lopsided. Please help! Other than this crack, that branch seems to be healthy and happy. The tree is all of 3 feet tall, and is probably about 3 1/2 years old. I suspect that this crack has been there for some time. Would a small bolt with a few washers be the answer?

Thanks in advance for any advice you may have.

I once had a shrub that split. I tried wrapping the two sides of the branch on either side of the split tightly together with a material that wouldn't cut into the bark. Eventually, the two sides of the split grew back together. I would avoid putting any bolts into the tree.
You might post your question on the Trees forum in hopes that an arborist might see it.

Bolting or cabling is very common to salvage split branching or to prevent against further damage. There were multiple discussions on this topic here a couple of seasons ago after a heavy, wet snowfall and a lot of damage to weeping laceleaf maples (which tend to accumulate and hold snow in their branches).

Do a Google search on "tree bolting or cabling" - you'll find various resources and videos showing you precisely how to do so. Contrary to what many think, if a split branch or fork is not immediately addressed (within 24-36 hours), the tree begins to compartmentalize amd seal off the injury and if that happens, the split will never grow back together and will remain a structural weakness and liable to further damage.

IMO, cabling or bolting in this situation is the ONLY way to go.
