How to Repair a Torn Branch on a Cedar Tree
- 1). Reduce the weight on the end of the torn branch by pruning a third of its foliage away with pruning shears. If the split is low on the trunk of the tree, prune upper branches from the weaker side. This will also direct the tree's energy toward repairing the wound instead of trying to feed leaves and twigs at the end of the branch.
- 2). Trim back torn bark at the edges of the wound to healthy, fresh wood with a sharp utility knife. Leaving bits of torn bark will collect moisture and inhibit healing. Raise the branch to join the sides of the split together. If the branch is large, use a block and tackle. If the limb is small, lift and secure it to a higher branch with cable or clothesline. Think of it as putting a broken arm in a sling.
- 3). Get several long, threaded brace rods with nuts for either end at the hardware store. Drill a hole through both sides of the split using a drill bit that is 1/16th inch smaller than the rod. If the split is deep, install more than one brace rod.
- 4). Install the rod, tapping it through the hole with a hammer. Cap both ends with nuts, and secure them tightly with a crescent wrench.
- 5). Wrap the wound with plastic wrap and secure it with electrical tape to keep moisture and insects out while the branch heals. Check it periodically for the next few weeks, and remove it after a month.
