1. It's a Keeper
If damage is relatively slight, prune any broken branches, repair torn bark or rough edges around wounds, and let the tree begin the process of wound repair.
Too Young to Die
Young trees can sustain quite a bit of damage and still recover quickly. If the leader is intact and the structure for future branching remains, remove the broken branches and let the tree seal the wounds and recover. Trees less than 15 feet tall that are leaning may survive if pulled back into place and staked for up to a year. Be sure to press out air spaces in loose soil.

Don't Try to Do It All Alone
Some of your trees may have damage that's too close to call, or may have hidden damage. You may need a tree professional to help you decide what to do. Don't hire just anyone who shows up at your door following a storm. Look for qualified arborists or contact your city forester.
