Can a fig tree survive if the bark has been chewed by mice?

It depends on the extent of the damage. If the bark has only been chewed off in a few places, usually these can callus off and the tree should recover. However, if the bark has been chewed off all the way around the trunk, or if the damage is extensive, the tree will likely not survive.

To help a fig tree that has been damaged by mice, you should:

Remove any dead or damaged tissue from the tree.

Apply a wound dressing to the injured area. This can help to protect the tree from infection and disease.

Water the tree regularly, especially during dry spells.

Fertilize the tree according to the package directions.

With proper care, a fig tree that has been damaged by mice may be able to recover and continue to produce fruit.
