How to use coffee grounds in the garden

Coffee grounds can be a great addition to your garden soil as they are a natural source of nitrogen, a nutrient that is essential for healthy plant growth. Here are a few ways you can use coffee grounds in the garden:

  1. Mix coffee grounds into the soil: You can mix coffee grounds into the soil around your plants to give them an extra boost of nitrogen.
  2. Use as a mulch: Spread a thin layer of coffee grounds around the base of your plants to help retain moisture and suppress weeds.
  3. Compost with coffee grounds: Add coffee grounds to your compost pile to help speed up the decomposition process.
  4. Repel pests: Some gardeners swear by the pest-repelling properties of coffee grounds. Sprinkling coffee grounds around the base of your plants may help keep slugs and snails at bay.
  5. Fertilize acid-loving plants: Coffee grounds are slightly acidic, so they can be especially beneficial for acid-loving plants like tomatoes, blueberries, peppers, carrots and roses.

Remember to use coffee grounds sparingly, as they can also make the soil too acidic if used in excess. It's also a good idea to mix coffee grounds with other organic matter, such as leaves and grass clippings, to create a more balanced compost.

Here's how to make a simple coffee ground fertilizer:

  1. Collect used coffee grounds: Save up your used coffee grounds in a container or bag in the freezer to prevent them from becoming moldy. You can also ask your local coffee shop if they have any used grounds they would be willing to give you.
  2. Mix with water: For every cup of coffee grounds, mix in one gallon of water.
  3. Let the mixture steep: Let the mixture steep for a few hours or overnight to allow the grounds to fully saturate with water.
  4. Strain the mixture: Strain the mixture through a fine-mesh sieve or cheesecloth to remove any large particles.
  5. Dilute the mixture: Dilute the mixture with an equal amount of water, as the concentrated coffee ground fertilizer may be too strong for your plants.
  6. Apply to your plants: You can apply the coffee ground fertilizer directly to the soil around your plants or use it as a foliar spray. Be sure to apply the fertilizer in the morning, as the plants will be able to better absorb the nutrients.
