Transform your kitchen scraps into a powerful, eco-friendly fertilizer by combining leftover coffee grounds with two common kitchen scraps. This DIY project not only reduces waste but also produces a nutrient-rich compost tea fertilizer that can invigorate your garden. By recycling these ingredients, you create a sustainable solution that enriches your plants and supports healthy growth.
Display your DIY compost tea in clear glass bottles or jars on a kitchen windowsill or garden shelf. Coordinate the display with earth-toned decor, such as terracotta pots or wooden plant stands, to enhance the natural aesthetic. Ensure the setting is bright and inviting, perhaps with a small indoor plant nearby to showcase the fertilizer's intended use.
Coffee Grounds Compost Tea Fertilizer

Materials
1 cup of used coffee grounds
1 banana peel, chopped
1 eggshell, crushed
1-gallon container with lid
1-gallon of water
Fine mesh strainer
Plastic or glass bottle for storage
Directions
1. Start by collecting 1 cup of used coffee grounds and place them in a 1-gallon container.
2. Add one chopped banana peel to the container to provide additional nutrients.
3. Crush an eggshell and add it to the mixture for calcium enrichment.
4. Fill the container with 1 gallon of water, ensuring the scraps are fully submerged.
5. Secure the lid on the container and place it in a warm, shaded area for 2-3 weeks.
6. Stir the mixture every few days to help the ingredients break down.
7. After 2-3 weeks, strain the mixture using a fine mesh strainer to separate the liquid from the solids.
8. Transfer the strained liquid into a plastic or glass bottle for storage.
9. Use the compost tea as a fertilizer by diluting it with water at a 1:10 ratio before applying it to your plants.

Variations & Tips
For a variation, consider adding a tablespoon of molasses to the mixture during the fermentation process to boost microbial activity and enhance nutrient availability. Alternatively, you can experiment with adding other kitchen scraps such as vegetable peels or apple cores, adjusting the recipe based on what is available. Always ensure the scraps are chopped finely to accelerate decomposition.
