How to Kill Iron Moss


Iron Moss, like most other species of moss, grows in areas where there is plenty of moisture and low light. Moss is a simple plant with no root system that grows in a dense mat. It is not an invasive plant, so it will not crowd out other growing species. Instead it grows in places that other plants will not grow, such as the floor of a forest and the sides of trees and rocks along with lichen. If Iron moss is growing in your landscape where it is not wanted, you can easily kill it and prevent it from growing back.

Step 1

Pour apple cider vinegar into a spray bottle.

Step 2

Mist or spray the moss with the vinegar.

Step 3

Continue to spray moss daily until it dies and turns brown.

Step 4

Remove moss from your landscape by "combing" it with a cultivating fork until the moss detaches from the surface. Discard dead moss.

Step 5

Prune back any plants that shade the mossy area so that it receives more sunlight. This will prevent moss from returning.
