Coffee Grounds

Used coffee grounds are an excellent addition to your garden as they are rich in nitrogen, which is essential for plant growth. Simply sprinkle the grounds directly onto the soil or mix them into compost to enrich it. They can help improve soil texture and water retention while also attracting earthworms. Be sure not to use too many at once, as high acidity could affect some plants.

This easy-to-use ingredient makes an effective and environmentally friendly fertilizer.

Eggshells

Eggshells are a great source of calcium for your garden, which helps strengthen plant cell walls and promotes healthy growth. Crush the shells and sprinkle them around the base of your plants or mix them into the soil. This can help prevent blossom end rot in tomatoes and peppers, which is caused by calcium deficiency. Eggshells also break down slowly, providing a steady source of nutrients over time.

These shells also serve as a natural pest deterrent, as their sharp edges can discourage slugs and snails from entering your garden. They decompose into a nutrient-rich substance that improves soil structure. For even better results, you can combine crushed eggshells with compost to enhance its benefits. Eggshells are a simple, low-cost way to improve your garden’s health.

Banana Peels

Banana peels are packed with potassium, phosphorus, and calcium, making them a great addition to your compost or directly into the soil. Simply chop the peels into small pieces and bury them under the soil around your plants. These nutrients help promote strong root development and flower production. They also break down quickly, providing a steady release of nutrients.

Banana peels are especially beneficial for flowering plants, such as roses, as potassium encourages blooming. The natural sugars in the peel also help attract beneficial microorganisms to the soil. In addition, they provide an excellent way to recycle kitchen waste into something valuable for your garden. This easy-to-use fertilizer is both effective and eco-friendly.

Tea Bags

Used tea bags are rich in nutrients such as nitrogen, potassium, and phosphorous, which are vital for plant growth.
