Remove moss and weeds from your lawn
A mossy lawn is a common problem – but it’s also a sign that your grass isn’t thriving. The same goes for weeds, which often appear where the grass is sparse or the soil is compacted. Fortunately, there are several effective measures you can take, whether you want to remove moss or get rid of dandelions, clover, and other weeds.
Why does moss grow in lawns?
Moss thrives where grass struggles. Common causes include:
Poor drainage or damp soil
Shade (moss doesn’t need sunlight)
Lack of nutrients
Uneven mowing height or cutting too short
Hot, dry conditions – grass weakens, moss takes over
You may also get moss if the soil is too acidic – which is common in older or compacted lawns. To prevent this, regularly overseed, mow at the right height, and lime the soil if the pH is low.

How to remove moss from your lawn
To effectively remove moss, combine several actions:
Scarify or dethatch the lawn to remove moss buildup.
Lime the lawn if the pH is low – e.g., with calcium nitrate.
Fertilize with a nitrogen-rich lawn fertilizer.
Overseed areas where the grass is thin.
Water regularly during dry periods – but don’t overwater.

Common lawn weeds – and how to get rid of them
Unwanted weeds are often a sign that the grass is too sparse. Here are some common types – and how to tackle them:
Clover: Weak-growing grass allows clover to take over. Support the grass with fertilization and overseeding.
Dandelions & thistles: Dig out by the roots, especially after rain.
Plantain, couch grass, chickweed & yarrow: Require regular mowing and sometimes spot removal with a weeding tool.
Micro clover & white clover: Tolerate mowing well but can be outcompeted by dense grass.
How to prevent moss and weeds
To keep your lawn free from moss and minimize weeds, maintain it year-round:
Overseed in spring and autumn – helps prevent moss from establishing.
Lime if needed to raise the soil’s pH.
Aerate once a year with a hollow tine aerator or spike aerator.
Mow regularly but not too short.
Fertilize in the right amounts – grass needs nutrients to outcompete weeds.

Frequently asked questions about moss in lawns:
What is the best moss control product for lawns?
There are several effective options. Iron sulfate is a classic, while Algomin’s “Less Mossy Lawn” is a popular long-term choice. Choose a product based on moss type, area size, and whether you prefer to avoid chemicals.
How can I remove moss without chemicals?
Scarify the lawn and lime if necessary. Follow up with fertilizing and overseeding to help the grass naturally outcompete the moss.
When is the best time to overseed a lawn?
In spring (April–May) and autumn (August–September). Soil is warm and moist, giving grass the best chance to grow.
Should I lime my lawn to reduce moss?
Yes, if the soil is acidic (low pH). Liming helps balance the pH and makes it harder for moss to thrive. Calcium nitrate is a good option that also provides nitrogen.
Can I have moss instead of grass?
Yes, in shaded areas moss can be a conscious design choice. But it requires different maintenance and isn’t suitable for play or heavy use.
What’s the difference between dethatching and scarifying?
Both remove moss, but scarifying goes deeper and improves soil structure. A dethatcher is easier to use but only removes surface buildup.
