Compost coffee grounds for your plants
Did you know coffee grounds can provide NPK [1] nutrients and many micronutrients to your plants, but only after composting?
Why do I compost coffee grounds?
Coffee grounds are finely textured and compact easily. This limits their use as a mulch on soil because they can stop air and water reaching the ground. They are also mildly acidic, which can be a problem for some plants.
Composting the grounds solves both of these problems, removing the acidity and breaking them down into a soil-like consistency.
Importantly, composting efficiently unlocks nutrients in spent grounds for reuse.
Home composting diverts coffee grounds from landfill while reusing their nutrients for your plants.
How do I compost coffee grounds?
Add spent grounds from your daily coffee fix to your mix of everyday kitchen scraps to be composted. This increases the amount and variety of nutrients in the total waste, helping you to create richer compost.
Limit coffee grounds to less than a quarter (25%) of the total waste because excessive amounts are disruptive to composting.
Put the waste in a kitchen composter like Bioverter either daily, or every few days with what you have gathered in a kitchen caddy.
Composting everyday kitchen waste is made easy with Bioverter, which is designed to solve traditional composting problems such as limiting your scraps input and frequent mixing. You can now use kitchen scraps as the main waste, and make compost without a need to aerate by mixing.
