How to Bolt a Split Tree Trunk for Structural Support

Saving a Split Redbud

An 8-inch trunk split down the middle with both sides alive can be stabilized with bolts.

Procedure

1. Pull halves together with rope and strong helpers.
2. Buy three ½-inch diameter bolts (appropriate length), six wide washers, six nuts.
3. Drill three equally spaced holes through both halves with a ½-inch electrician's bit.
4. Insert bolts with washers on both ends; secure with two nuts each.
5. Tighten all bolts, then remove rope.

The halves won't graft back together, but the tree should live several more years.
