So, why should you consider using coffee grounds as fertilizer? Here are some compelling reasons:

  • Improves Soil Structure: They help improve soil aeration and drainage, making it better for plant roots.

How to Use Coffee Grounds in Your Garden

Now that you know the benefits, let’s explore how to use coffee grounds effectively:

1. Mix with Compost

One of the best ways to use coffee grounds is to mix them with your compost. They add extra nitrogen, which helps break down other materials in your compost pile. Just sprinkle them in as you add other compostable items, like fruit peels and leaves. For more specialized tips on using coffee grounds for specific plants like midge plants, check out this guide.

2. Directly in the Soil

If you’re planting directly in your garden, you can work the coffee grounds into the soil. This will help add nutrients right where your plants need them. Just ensure you don't add too much!

3. Use as a Mulch

Spread a thin layer of coffee grounds around your plants as a mulch. This helps keep the soil moist and adds nutrients as it breaks down. Remember to mix them with other types of mulch for the best results.
