There are many different ways you can use coffee grounds in your garden. I use coffee grounds for composting, homemade fertilizer, natural pest control, and SO much more. If you don't drink coffee, don't worry! The grounds do not have to be brewed in order to work for you. I have used coffee grounds both ways and have always had success. Here are 9 ways coffee grounds can benefit your garden...
Because coffee grounds have a 20 to 1 ratio of nitrogen to carbon, they are ideal for composting.They also provide potassium, phosphorus, magnesium, copper, and other beneficial minerals.
2. Pest Control
This is the easiest and most beneficial thing you can do for your plants. Simply line your garden with coffee grounds to fight off slugs, snails, ants, rabbits, squirrels and so on. If you notice your fruits & veggies are getting eaten by bugs, make mounds of coffee grounds around the plant for a good defense against the intruders!
I never, ever, ever, like Taylor Swift amounts of never, ever's, thought I would have a worm farm. Yet, here I am, telling you how awesome these little creatures are. Worms do the work for you by turning the soil. All you need to do is put some worms in a bucket with soil and coffee grounds. Let them work for a bit, then spread the mixture evenly around your garden. So simple and kind of gross, but it works and saves you time!
Again, this is a super easy trick. All you have to do is sprinkle some coffee grounds on the soil and let nature do the rest! The coffee grounds will fight off harmful fungus and mold that could be attacking your plants. The coffee grounds will create a "helpful" kind of fungus on its own that will benefit your plants.
5. Plant Food (homemade fertilizer)
This is probably the number one way I use coffee grounds in my garden. My plants love it! I love it too, because unlike pricey store bought fertilizer, this is safe for the kids to play in the garden. Method: Measure 1 cup of coffee grounds to 1 gallon of water. Let it sit for at least 24 hours or so. Once the water is dark in color you can pour it directly onto the soil at the base of your plants. I do this a lot for my seedlings to give them a strong start at life. A little goes along way...
6. Roses, Hydrangeas, & Nitrogen Loving Plants
Adding coffee grounds to your soil will make these nitrogen loving plants blossom and thrive. This is beneficial for many of the same reasons I've already listed. The coffee grounds will attract worms while fighting off harmful fungus and pests.
7. Carrots, Tomatoes, & Acid Loving Plants
Place coffee grounds around the soil of your acid loving plants such as raspberries or blueberries. The acid from the grounds will boost the acid level in your soil and stimulate your produce. This boost of energy will cause your plants to flourish. The neutral to acidic pH level is heaven for your flower beds!
I love cats and think this might be the first time I have ever NOT wanted cats around;) If you have a cat "problem," try putting coffee grounds in the soil to safely turn cats away from digging in your garden.
This is something I haven't actually tried myself. We have never had a gopher problem, but a close friend of mine did. She used her brewed coffee grounds to fill the gopher holes and apparently that worked! If anyone has tried this, feel free to let me know about your experience in the comments below.
