Clorox kills off germs, fungi and microbes.

Tree fungus is an unsightly tree condition that causes discolorations, abnormal growth patterns and abscesses on certain trees. Tree fungus can sicken a tree and even kill it. This can be prevented by killing the fungus that is hurting the tree. You can kill tree fungus by dousing the affected area with a solution of Clorox bleach and water.


Step 1

Fill a bucket with 1 quart of water.

Step 2

Pour 1 cup of Clorox bleach into the water and mix it well with a long-handled spoon.

Step 3

Take the top off a spray bottle and place a funnel into the bottle. Pour the bleach-water mix into the bottle through the funnel until it is full. Screw the top back onto the bottle.


Step 4

Spray the area of the tree affected by the fungus thoroughly. Allow the Clorox-water solution to dry onto the tree. The bleach water will kill the unwanted fungus but will not harm the tree.

Step 5

Repeat as necessary up to three times per day until the fungus has been eliminated.
