Savor Those Coffee Grounds
- Love coffee? Well, drink up – but don’t throw those grounds out with the trash. Gardening Junkys know there really is more to coffee than just drinking it. It turns out coffee can play a part in organic gardening. So not only can you drink it, but you can use the coffee grounds to make your garden soil and plants happy.
Brewed coffee is acidic, but the grounds produced from the brew are not. The brewing process removes the acid and they become neutral and nitrogen-rich. This is good news and lends itself to practical applications in your garden.
Probably the easiest thing to do with your coffee grounds is to add them to your compost pile. They are considered a “green” material just like any vegetable peelings and grass clippings. Being rich in nitrogen means they will help heat up your compost and aid in a faster decomposing time. As with any composting, brown materials such as dry leaves should be in your bin as well.
Another way to use your grounds is to work them well into the soil before you plant your garden. Or consider lightly sprinkling them around your garden before a good watering as if they were a slow-release nitrogen fertilizer.
Consider making a compost tea with the remains. Try grounds and water for a weak mix and let it heat up. Strain it and spray on the plant leaves. You might want to do a test run first to make sure it’s not too strong.
Some people like to spread coffee grounds around their acid-loving plants, but since the coffee’s acid was depleted in the brewing process, it may not really give extra help to these plants. There are those who swear by it though.
If crawling pests are a problem, try spreading grounds and crushed egg shells around plants in an effort to deter pests such as slugs.
Feed the worms, they like coffee too! If you have a worm bin you can feed it to them in small doses mixed in with your other kitchen scraps. If you don’t have a worm bin, working it into your pile or directly into your soil will benefit the wrigglers who will, in turn, benefit your soil.
You can keep a compost bucket in the kitchen for your grounds after you brew your coffee and then dump them all into your compost bin at the end of the week. Alternatively, you can get larger quantities by visiting your local coffee shops and asking for their grounds. Consider making arrangements to pick up their waste on a specific day each week and they’ll keep you “grounded”. Do watch your ratio though, as it should not be more than 20-25% of your total compost material.
The next time you have coffee, save the remains for the benefit of your garden. Put them in your compost pile, feed the worms, work into the soil, or use in a tea, and watch your plants thrive.
