Step 1

ASSESS SPLIT -- Is there enough bark on each side of the split? If not, then the side with little or no bark will eventually die, since the part directly under the bark is what feeds the branches and leaves.

Step 2

DETERMINE SUPPORT -- You need to be able to force the split back together somehow, and hold it in place for several years as the tree grows around the split. For larger trees, you can do this with a winch and rope or cables (B) to winch the halves back together above the split.

Step 3

APPLY GLUE -- With the support method determined, I opened up the split and used a popsicle stick to apply the glue to both sides of the split. You can see the glue starting to expand and fill in the space in the picture.

Step 4

PROVIDE SUPPORT -- Then, I tied the branches above the split so that I could pull the split back together so that the glue can cure. I wrapped some twine around the trunk temporarily while the glue sets up and hardens. I will remove this in a day, since I don't want to girdle and kill the tree.

Step 5

INSTALL BOLT/NUT -- I have to admit now, after several weeks the glue did not hold. The trunk will need to be held together for a couple seasons so that the bark will grow around the split. So I held the trunk together and used a spade drill bit to drill a 3/16" hole through the trunk.
