Why Have All These Mushrooms Appeared on My Lawn?

Cool, damp weather after bouts of high heat encourages mushrooms to grow in lawns in Ontario. High, lingering overnight humidity and dampness is also an open invitation to fungus growth, so we strongly discourage watering in the evening.

After some long and heavy soaking rains in Late August and September, we have seen an unusual amount of mushrooms sprouting in Ontario this year.

Mushrooms

Mushrooms come in a huge variety and are not harmful to your lawn.

Fungi are nature’s garbage crew. Mushrooms in your lawn are working to break down dead organic material and freeing up those nutrients for your grass to use.

Lawn mushrooms are just the fruiting bodies of the fungus. They’re the part that pops up above ground in your grass to spread spores around. Most of the mushroom in your grass is actually underground, busily eating up old bits of wood, dead grass and leftover roots of plants that have been removed. Even animal poop is fair game for fungus.

Fungus colonies grow outwards, forming “Fairy Rings” of mushrooms at their edges.

Removing Mushrooms In Your Lawn

You can easily kick, stomp, mow or rake the mushrooms in your lawn as they appear if you want rid of them. They will grow back though, as long as whatever decay the fungus is eating is in your soil, and the area is warm and damp enough for the fungus to grow.

If there is an old stump or buried construction debris, digging it out will remove the main source of your mushroom problem in your lawn.

How To Keep From Getting Mushrooms In Your Lawn

Because Ontario has such diverse weather patterns we can have times of year that are particularly conducive for mushroom growth. Good lawn cultural practices are still the best way to make your lawn unappealing to mushrooms.

  • Mow regularly so thatch does not build up. Do not leave long clippings (greater than 1″) on the lawn!
  • Aerate every year – the improved drainage and airflow that this practice develops will help prevent the soil from getting the kind of lingering damp that mushrooms love. LawnSavers can do this for you in Spring or Fall, starting at just $60.00 + HST. We service lawns throughout the Greater Toronto Area
  • Only water your lawn once a week- deeply, so your lawn has time to dry out in between lawn waterings.
  • Rake up any leaves, old mulch or other debris promptly so it doesn’t become fungus food.
