How to deal with moss my lawn and flower beds are covered in moss

Asked March 26, 2020, 11:59 AM EDT

My lawn and flower beds have a lot of moss. I know my soil is acidic. How do I treat it? Should I remove some of the soil from the beds and replace it. I plan on using gypsum, how much do I use?

Thank you for the question. Moss in the lawn and flower beds can indicate low fertility, low pH, shade, high soil moisture, and compaction. Fixing as many of these factors as you can will help. Gypsum can add calcium to your lawn but will not adjust the pH. LIme is required. The best way to determine how much lime is required is through a soil test (http://homesoiltest.msu.edu/). The test results will give you the appropriate application rate of lime as well as other major nutrients. This goes for both lawn and flower beds. If the soil is significantly different in those areas it is recommended to have two separate tests. Check out the following links:
