Over 2.25 billion cups of coffee are consumed daily all over the world making it one of the most most popular drinks. Many of us love to make it fresh at home, making lots of coffee grounds that are ideal for our composters as they are high in nitrogen, an essential nutrient for our soil. They also contain potassium and phosphorus which can help our plants thrive.
Whilst adding them to your compost heap has many benefits, it is important to add them in moderation due caffeine content and high moisture levels. Too much coffee grounds can cause unpleasant odours because of excess nitrogen levels.
It is recommended that no more than 20% of your compost heap is coffee grounds as it is important to keep your mixture balanced.
Coffee grounds can be sprinkled around the garden as they make a good repellent for slugs and snails. If you do have pets, do this sparingly as caffeine can be toxic to dogs if consumed in large amounts.
