Damaged tree bark can take a toll on the health of a tree. Not only does bark protect a tree from pests and diseases, it also contains the so-called phloem tissue, which is responsible for the transport of nutrients and water throughout the tree. Although reattaching the bark is sometimes an option with minor wounds, if the fallen or broken off bark is nowhere to be found, you’re next best thing it to properly clean the wound to promote the growth of new callus wood that will close up the wound.
Things You’ll Need
Assess the damage to the tree. If it takes up between 25 to 50 percent of the tree’s circumference, you can clean the wound. If less than 25 percent of the trunk’s circumference is damages, continue to care for the tree as normal, as it will most likely heal itself.
Place a chisel’s sharp blade about 1/2 inch above the ripped edge of the wound, and lightly hit the chisel’s other end with a hammer, chipping away the bark’s torn edge. Avoid hitting the chisel too hard. The goal is to remove the bark without damaging the tree’s wood.
Work all the way around the wound, making clean, straight cuts. Remove all the jagged edges so they can’t continue to rip and worsen the wound. Create an oval shape with rounded corners and a bottom and top that are slightly narrower than the sides.
