Which plants like coffee grounds? I’ve heard you can use them in the garden. Since we drink a lot of coffee at home, I’d like to try composting it, too.

We’re happy to hear you want to recycle your coffee grounds. Several plants thrive on nutrients and acid they get from coffee. You can also use grounds in compost, plus they work to repel some garden pests, too.
Since washed coffee grounds are close to neutral pH, adding them to the soil in your garden will increase the amount of nitrogen. They help the ground drain excess water better and retain moisture longer.
Although the grounds are not beneficial to tomatoes, their acidic content can help perennial food plants and vegetables like blueberries, roses, radishes, carrots, and hydrangeas flourish. Hydrangeas will blossom blue if you place coffee grounds in the soil around them.
Finally, coffee attracts earthworms that eat spider mites and aphids. It repels slugs and snails and might keep cats from using your garden as a litter box.
