4.3. In Compost

  • Boost Your Compost:
    Add coffee grounds to your compost pile as a “green” component, balancing carbon-rich materials (the “browns”) such as dry leaves or straw.
  • Ideal Ratio:
    Aim for about 20-30% coffee grounds in your compost mix for a well-balanced nutrient blend.

4.4. Direct Application Around Plants

  • Fertilizer Boost:
    Lightly sprinkle coffee grounds around the base of your plants, and gently work them into the topsoil for a slow-release nutrient boost.
  • Pest Deterrence:
    A thin layer around plant stems may also help deter pests like slugs and snails.

5. Best Plants for Coffee Grounds

  • Acid-Loving Plants:
    Blueberries, azaleas, and camellias thrive with the slight acidifying effect of coffee grounds.
  • Vegetables and Herbs:
    Tomatoes, carrots, basil, and mint benefit from the slow-release nutrients, leading to healthier growth and richer flavors.
  • Flowering Plants:
    Many annuals and perennials respond well to the added organic matter, resulting in enhanced vigor and more vibrant blooms.

6. Sustainable Usage and Precautions

  • Moderation is Key:
    Apply coffee grounds sparingly—a thin layer is generally enough to avoid excessive soil acidification.
