What moss in my lawn?
There are hundreds of species of mosses found in temperate climates. Only a few are troublesome as lawn weeds. Moss may be a problem whenever one or more of the following situations are present:
- Low levels of nitrogen
- Poor air circulation
- Excessive shade
- Low soil pH
- Poor drainage or compaction
- Low mowing height
- Any maintenance practice which puts stress on the grass plants
How can moss be prevented and treated?
The best way to control moss is to correct the underlying problem. These steps may include one or more of the following:
- Prune trees to reduce shade and increase air circulation
- Aerate to improve drainage
- Adjust mower to cut at or above 6 cm
- Apply regular applications of fertilizer to increase nitrogen
- Have your soil tested to determine soil pH…liming may be necessary to increase pH
If these changes do not rectify the problem, your Weed Man Professional may apply a moss treatment in the spring or fall. Once the moss turns black, it must be raked up and the bare areas should be top dressed and over seeded. (The moss control application may only be available in coastal regions.) Please contact your local Weed Man Professional for further information.
