How to Use Old Coffee Grounds



Coffee is a well-known beverage that is enjoyed in all parts of the world. People often do away with the coffee grounds once they are done brewing the coffee. After going through this article, you may not want to throw away coffee again.

Many people are finding the many uses of the used or old coffee grounds,  and coffee beans around the garden and in your home. If you are someone who doesn’t drink coffee, you might not have enough grounds at home. However, you can visit large coffee stores where coffee is sold out in large quantities; they have enough grounds to give out to you. In this article, I have highlighted 16 things you can use your old coffee grounds for.

1. Fertilize Your Garden

Most of the soil that we have around doesn’t actually have the nutrients they need for adequate growth. Also, as these plants grow, they take up nutrients from the soil for their use and in the process leave the soil deficient in nutrients.

This is the reason most of the garden soil needs to be fertilized so the nutrients needed for plant growth can be added. Some nutrients needed include chromium, magnesium, potassium, calcium, nitrogen, phosphorus, and iron.


The plants growing on the soil can also take up some heavy metals in the soil which can be harmful to the soil. So what is the effect of coffee on your soil? The coffee attracts worms to the soil.

These worms are good for the soil as their activities add nutrients to the soil. If you want to use your coffee as fertilizer for your soil, all you have to do is sprinkle it on the soil around your plants.


2. Compost it for Later Use

If you don’t want to use your coffee immediately as fertilizer for your plants, you can compost it so you can use them later. The process of composting is one that occurs naturally. This is a process that converts food items into dark rich material called humus or compost.

When you add compost to your soil, it helps retain more water and nutrients, and this is beneficial to the plant and the soil. Studies have shown that compost that’s made with items from the kitchen and coffee contains a lot of nutrients when compared to others.

A study was carried out with compost containing a different percentage of coffee; it was found out that the one with the highest percentage of coffee is the best.

3. Repel Insects and Pests

To use your coffee as an insect repellent, all you have to do is bring it out and sprinkle it around the areas where the insects live. You can also prevent insects from affecting your plant by sprinkling some coffee around the plant. This will prevent crawling pests from attacking your plant.


4. Remove Fleas from Your Pet

One of the major problems of keeping flea is the flea infection they have. Flea infection can be very expensive to treat and it takes a time to treat. There are a lot of chemicals out there that can be used to treat fleas, but most of them will later have an adverse effect on the pets.

Luckily for us, coffee is toxic for fleas, which makes it an option for removing flea. Add shampoo to the fur of your pet, then rub the coffee on their body; after this wash off the coffee and shampoo and leave the animal to dry up.

Many people think that coffee has a shining effect on the fur of the animal, but there is no research to back it up. Coffee might not be less effective as other chemicals, but much healthier to use; so after you have tried it and it’s not as effective, you can consult your vet. The coffee should only be used externally.

5. Neutralize Odors

I am a coffee addict, but most times prefer my instant coffee to coffee grounds. maybe because I want it ready made. but nothing compares to the natural aroma and deep natural taste of the grounds. and the gardening part I never thought of. i think I may consider putting in the efforts you describe here. But what of some of us that like chewing coffee beans? Just asking.
