Question from Mary in Mary, L’Orignal, Ont.
How do you get rid of moss? I have tried everything I can think of and nothing seems to work. I had several large spruce trees removed to provide more light and I just got more and thicker moss. There is a large cedar hedge around the yard, but lots of sun. The earth is heavy clay and acidic. I have used a heavy rake to almost denude the area, taking out many construction-size bags of moss and it just increases. None of the commercial sprays work, either. It has even destroyed newly laid turf.
This is a conundrum. We’ve not encountered moss that is as persistent as you describe.
Moss thrives in conditions with acidic, compacted soil, which sounds like the conditions you have. Here are two suggestions:
- Have your soil tested to see if there are any nutrient deficiencies (omafra.gov.on.ca/english/crops/resource/soillabs.htm lists soil testing laboratories in Ontario) that might be inhibiting your turf and encouraging the moss.
- Loosen the soil so it’s not compacted and incorporate plenty of organic matter, such as compost, good topsoil and/or leaf mould — not peat moss, because it’s acidic.
You may also want to consult an experienced lawn care service in your area to see what might be suggested.
