Whether you make your daily cup of coffee with a french press, a pour-over Chemex, or a classic coffee maker, you probably find yourself with a surplus of coffee grounds pretty often. Some people dispose of them by throwing down the garbage disposal, flushing them down the toilet, or tossing them in the trash — but those methods all have their drawbacks, and are not recommended. Coffee grounds can clog the sink or the toilet, causing plumbing issues; and when you put them in the trash, they will go to the landfill, emitting greenhouse gases such as methane.

Most environmentally conscious coffee drinkers probably throw their grounds in the compost, which is a great zero-waste option. However, coffee grounds are actually a valuable resource when it comes to your garden beyond the compost pile. So if you’re a home gardener, read on for all the things you can do with coffee grounds in your garden.
