What To Do With Coffee Grounds In The Garden

There are multiple uses for old coffee grounds in your garden, which is one of my favorite uses for them.

Add It To Your Compost Pile

Spent grounds contain nitrogen, calcium, phosphorus, potassium and many more nutrients, making it a great addition to your compost.

The coffee grounds will also help with water retention. It is suggested that you don’t use more than 20% coffee in your compost mix.

Even though 40% mix produces the least amount of greenhouse gasses, more than 20% can turn your soil acidic.

Add Them To Your Worm Farm

All gardens need a worm farm of some kind. Your worm farm can be run in conjunction with your compost pile. In my opinion, a separate mini worm farm is essential.

Worms are life which is exactly what every thriving garden and farm needs.

Your worms will eat your coffee grounds and poop them out, helping you to create high-quality new soil full of nutrients.

Use Them To Repel Pests And Insects

You can use your coffee waste and use it to keep pests like snails and slugs away from your plants and veggies.

You can also manage beetles, fruit flies, mosquitoes and ants. In my own experience, fresh coffee grounds work best for this with Italian roast being better.

Sprinkle them around your plants and vegetables where you see pests and create a barrier that they hate to crawl over.

Use It As A Garden Fertilizer

If and when your soil is lacking nutrients, you can help to kick-start it by liberally spreading your old dried coffee ground liberally around your garden and on your potted plants.

It is best to spread it and then lightly rake in your old coffee beans too. It’s organic material that will help add nutrients and help your soil to retain moisture.

The nutrients in your used coffee grounds are great for plant growth.

Make A Liquid Fertilizer

Brew a second cup of coffee or a carafe of coffee with your spent coffee grounds. Make as much as you need, even a few liters.

Save it and let it cool down. Sprinkle your cool rebrewed coffee on your plants in your garden and house, even your lawn.

As a bonus, you can still use the grounds and get a thirsty use from them by using them in your worm farm or compost pile.

How To Use Coffee Grounds As Fertilizer

Using coffee grounds as a fertilizer brings you more than one option: you have multiple options.

As a keen organic urban farmer, it’s all about the quality of your soil and what you put into it to ensure that there is plenty of life, insects, worms, microbiome, bacteria and so on.

Coffee grounds are a great and popular option as they tick all the right boxes.

  • Full of nutrients.
  • Contains nitrogen.
  • Helps to retain moisture.

The neat slow release of nitrogen over time is what I love!

There are a few ways of using coffee grounds as fertilizer, but don’t use too much as you don’t want to spoil the soil pH.

The way that works best is to use a combination of all methods or to cycle through the methods.

The methods are:

  • Brew coffee to make a liquid fertilizer.
  • Add them to your compost pile to create quality new soil.
  • Add them to your worm farm to create fresh new high quality soil.
  • Sprinkle them and mix lightly into your top soil.

Whichever method you use, it is important not to over do it as coffee is acidic, and you don’t want to upset the soil pH. You must maintain an alkaline soil.

What To Do With Coffee Grounds For Plants

For house plants, the best way that I find is to remove your plant from the pot temporarily and mix the coffee grounds into the soil. This is something to do just for the first time to get a good distribution through the soil.

Subsequent additions of coffee grounds can be added every second or third day to avoid acidification of your soil.

If you are concerned about acidification of your soil, add a sprinkle of bicarbonate of soda.

Use the same technique with your garden plants and vegetables.

You can also rebrew your used coffee grounds and use them as a liquid fertilizer when it cools down. This is good for getting nitrogen deep into your soil.
