I think it’s safe to say that we all love and enjoy brewing our coffee in the morning. Nothing beats the anticipation and excitement of that first drop of coffee on your tongue that rejuvenates you from your night’s slumber.  But what do you do with the leftover coffee grounds? Did you know that there are uses for used coffee grounds?

Many people resort to just binning or rinsing out their used coffee grounds into the sink. Did you know that used coffee grounds have many practical uses around the house? For example, they are excellent for your garden, compost and work great for neutralizing odours. Let’s take a look at all the practical uses for used coffee grounds.

The Uses For Used Coffee Grounds Outdoors And In the Garden

Coffee Ground Compost

Discard your used coffee grounds into your compost. Coffee grounds are considered green compost and are rich in nitrogen (1.45%) and many other nutrients. If you are going to be using coffee grounds for compost, just make sure you have a balance with brown compost. You should have a 4:1 ratio of brown compost to green compost. Having too much green compost will result in smelly compost, and not having enough will prevent the pile from heating up.

Coffee Grounds In Garden

Used Coffee Grounds For The Garden

Using coffee grounds in the garden as a fertilizer is a great way to give your garden essential nutrients for plant growth. When plants grow, they absorb all the valuable nutrients from the soil eventually consuming all of the soil’s nutrients. So keeping an eye on the garden’s fertilization is important. Ground coffee can also aid with the absorption of heavy metals that tend to contaminate the soil. (1

Some of the essential nutrients that coffee grounds hold for plant growth are: 

  • Calcium
  • Iron
  • Potassium,
  • Magnesium,
  • Phosphorus
  • Nitrogen
  • Chromium

As you can see, used coffee grounds can offer your garden quite a lot! It also attracts worms to your garden which works in your favour since the worm’s waste known as “castings” offer the same type of nutrients as coffee does! 

To use coffee grounds in your garden, simply sprinkle the grounds over the top of the soil, you can also scratch the grounds in an inch deep into the soil for faster absorption. If you’re looking to do a large batch, you can create a “coffee ground tea”. For this, you will require a large bucket (with 5 gallons of water) mixed with two cups of used coffee grounds. Once mixed properly, let the mixture sit for a few hours or overnight. This will create a wonderful liquid fertilizer that you can use all around your garden.
