The next time you finish your morning coffee, think twice before you toss those used coffee grounds into the trash. Coffee grounds have many uses in the garden. They enrich the soil with nitrogen, potassium and other minerals, improve soil quality, and plant growth.
Add coffee grounds to your composting bin. They’re a valuable source of nitrogen.
2. Pest Control
A barrier of coffee grounds around the plants may protect them from slugs and snails.
3. Cat Repellent
Put coffee grounds in the soil to keep cats away from digging in your garden.
4. Acid-Loving Plants
Place coffee grounds around the soil of your acid-loving plants such as roses, rhododendrons, fothergillas, holly, gardenias and so on. Coffee grounds increase acidity and nutrients in the soil.
5. Easy Fertilizer
Add 2 cups of coffee grounds to a 5 gallon bucket of water and allow it to steep overnight. Mixing these two ingredients is one of the simplest ways to make your own homemade fertilizer.
Using coffee grounds as a mulch can help controlling weeds and keep your vegetable plants more hydrated during the heat of the day.
7. Boost Carrot & Radish Harvest
Double your harvest of carrot and radish, mixing your carrot and radish seeds liberally with coffee grounds.
