Although worms may seem like they could damage your lawn, they are actually very good for your lawn’s health.
Earthworms, to be more specific, are fantastic for the health of your lawn as they busily work away beneath the surface. The sign of worms shows that your soil is in good health with a good balance of organic material. If anything, it is more of a concern if worms are not in your soil, as this shows that the soil is lacking in nutrients.
What are the benefits of worms in my lawn?
Worms break down the thatch

Creating usable nitrogen in the soil
Increased decomposition of the soil
Why would people think worms were a problem in lawns?
The main reason people can be concerned by worms is mainly when they come to the surface during Spring and Autumn in Melbourne. During these seasons in Melbourne, the moisture content in the soil is increased, therefore earthworms rise to the surface and start leaving castings, also known as mud balls. Castings are small mounds of worm excrement or digested organic matter, which is beneficial for your lawn. The only issue that may concern some people is the messy appearance of these castings on top of their lawn.
Is their anything I can do about earthworm castings?
Yes, there is. When the castings are dry, you can rake across the lawn to distribute them easily. This can also be beneficial, as like organic fertiliser, this will settle the castings into the roots and provide nutrition for your lawn. You may also want to mow your lawn slightly higher during this time to reduce the appearance of these castings.
So, although not the cutest species in your garden, the humble worm is most certainly a friend to your lawn. Next time you see them in your soil, smile and give yourself a pat on the back for supplying a good balance for both them and your lawn to live happily ever after.
