Are coffee grounds good for my garden turf?

You might have heard about coffee grounds being used to feed the garden turf on your lawn. But, do they really work?

In this short article, we’ll answer some of the common questions people ask about the seemingly strange idea of using coffee grounds to feed their lawn, including:

  • What are coffee grounds?
  • Do coffee grounds really help feed a lawn?
  • What’s the best way to apply coffee grounds to your lawn?

What are coffee grounds?

If you like and make you’re own real coffee, you’ll know exactly what coffee grounds are. But, for those who prefer the easier option of instant coffee, and have never operated a cafetiere, here’s a brief explanation.

To make fresh coffee, you need to grind the coffee beans and filter water through those ground beans to extract the delicious coffee. The coffee grounds are what’s left behind once the process is complete.

Traditionally regarded as waste, these coffee grounds have a surprising number of benefits to your lawn, including acting as a slow release fertiliser, packed with vital nutrients.

Do coffee grounds really help feed a lawn?

As we’ve already mentioned above, yes, coffee grounds really do help feed a lawn. They do it by slowly releasing three vital nutrients:

Nitrogen – Nitrogen is hugely important to your lawn, as it promotes healthy green grass, allowing the plant to turn light into vital sugars using a process called photosynthesis.

Phosphorous – Phosphorous is vital in helping your lawn establish a strong root system, and like nitrogen, it plays an important role in photosynthesis.

Magnesium – Magnesium is also one of the elements that helps the chlorophyll in your lawn capture sunlight in the photosynthesis process, and is also vital in the plants metabolism of carbohydrates.

Earthworms love coffee grounds too!

Apart from the slow-release fertilising properties of coffee grounds, another surprising benefit is that they help increase the number of earthworms in your soil, which in turn acts as a natural aerator – as long as you don’t mind a few more wormcasts.


What’s the best way to apply coffee grounds to your lawn?

Now you know the benefits coffee grounds can bring to your lawn and other plants, how do you apply them to your lawn? You could simply just scatter them by hand, but as coffee grounds can be quite acidic, it’s best use a method to get a more even spread, such as:

  • Using a lawn feed spreader – In the same way a mechanical lawn feed spreader spreads regular fertiliser, this method helps to create an even spread and helps to avoid clumping
  • Use a bucket – If you don’t have a lawn feed spreader, simply poke holes into an old bucket and use it scatter the coffee grounds to create an even spread.
  • Use a rake – If you want to just spread the coffee grounds by hand, make sure to use a rake to ensure a good, even spread.


A word of caution

Looking around the internet, you’ll come across articles claiming that coffee grounds can actually damage your lawn and shouldn’t be used. As with any lawncare technique, read widely on the subject, so that you can make an informed choice.
