1. Fertilize your Garden

One of the uses for coffee grounds is to grow plants

Coffee contains key minerals for plant growth. Here are some essential minerals contained in coffee that can help plants grow.

One of the uses for used coffee grounds is to help pH balance by turning the soil more acidic. This is because coffee is slightly acidic after brewing. However, if you rinse your coffee grounds after brewing you can turn them pH neutral and they will have no effect on the acidity levels of your soil.

To use coffee grounds as fertilizer just sprinkle thinly onto your soil or add them to a compost pile. If you are familiar with composting they are considered a “green” nitrogen-rich organic material. Make sure to balance the coffee grounds with enough “browns” like dried leave, wood, and newspaper. Small insects help break down this compost mix and turn it into a fertilizer that is safe for plants.

2. Composting

Worms love coffee grounds and that makes them a perfect candidate for composting. It is a natural process that turns your organic scraps into compost or humus. This can be used or stored.

By adding compost to your garden it can help soil and plants hold into nutrients and water. It has been proven that adding compost improves the health of your plants. Another study showed that compost made with coffee grounds was actually richer in nutrients than regular food wastes.

A batch of 40% coffee grounds and 60% other organic matter produced the fewest greenhouse gasses and highest quality compost.

3. Pest Repellent

Used coffee grounds still have many chemicals within them after brewing. Certain compounds such as caffeine and diterpenes are highly toxic to insects. Other pests simply do not like the smell of coffee. As a result, you can sprinkle coffee in areas you do not want pests to go to create a safe area. Squirrels, mosquitoes, slugs, and snails all dislike the smell of coffee.

One trick we use it we like setting out empty pots where we compost coffee grounds. This repels pests and makes useful humus for us to use later.

4. Burn Coffee Grounds as Mosquito Repellent

According to the EPA, using used coffee grounds is a safe and effective way to keep mosquitoes away. Like we said in our previous tip mosquitoes cannot stand the smell of coffee.

When you burn the coffee grounds it will keep all the flying pests away and extends the reach of the coffee smell. Insects also associate smoke with danger so the instinctively avoid smoke to find shelter elsewhere.

To do this safely you must start with dry coffee grounds. Place them in a bowl or plate and burn them as you would burn incense. Light one spot that you want to start burning. That’s all, now all you have to do is keep an eye on the embers!

You may need to set up a few of these for a large outdoor event, but it’s an extremely cheap way to repel mosquitoes especially if you have the coffee grounds on hand.

5. Purge Fleas From Your Home

When your pet has fleas it can be very costly to remove the insects from their fur. There are a lot of flea-removal products, but it usually has harsh chemicals, has side effects, and is expensive. It is also tough to apply.

You can use coffee grounds to remove fleas from your pets. Coffee grounds are a natural treatment because fleas don’t like coffee.

All you have to do is rub the coffee grounds thoroughly into the pet fur after washing. Leave it on for a few minutes while wet and then rinse and dry your dog as normal.

Coffee grounds have a multitude of uses for cleaning. Here are some of the popular uses.

You can use them to clean ashes from a wood-burning fireplace.
