Benefits Of Using Coffee Grounds In The Garden As Fertilizer
Is coffee good for plants? Yes. The benefits of coffee grounds in the garden are fourfold.
- Earthworm attraction
Aeration. Compacted soil is a problem for plants because the soil is compressed, meaning the roots of the plant are unable to get what they need. Aeration breaks up the soil and creates small holes through which oxygen, nutrients, and water can reach the roots. Healthy roots can become strong, and as a result, your plants strengthen.
Water Retention. Water retention is a problem in dry and arid regions, where droughts are common. Even drought resistant plants are unable to get enough water, and they end up wilting and dying. Coffee grounds improve water retention in soil, and improved water retention means the plants will be able to do more with less water.
Drainage. On the other end of the water retention spectrum, poor drainage creates stagnant water and leave your plants vulnerable to diseases.
Soil with good drainage ensures that the roots of the plant can receive the water they need while letting the excess flow away which helps to get rid of soil gnats. Coffee grounds help to break down the soil and allow for better drainage.
Earthworms. Love them or hate them, worms are fantastic for gardens. They move through the soil by tunneling, which creates natural vents through which oxygen and water can flow.

What about Soil pH?
You may have heard that coffee grounds will alter the pH level of your garden.
Deodorize Carpet From Pet Odors
Coffee grounds like to soak up all the odors around them. So, if you ever have an accident with your beloved pet, then put some dried coffee grounds into a filter, tie the filter at the top, and place it on top of a pet stain. Let the wrap sit on top of the stain overnight and watch it disappear. You can also use dried coffee grounds to remove the musky odor from the carpet. In order to do that, simply spread it on the carpet, let it sit for a few hours and use a powerful vacuum cleaner to revive your carpet.
Coffee Grounds Cockroach Trap
Apparently, cockroaches are attracted to the smell of coffee grounds .
Homesteady has instructions for making a DIY cockroach trap using old coffee grounds.

Coffee Grounds For Mulch
Spreading layers of coffee grounds as mulch is beneficial when in lower quantity. Coffee grounds shouldnt exceed more than 25% of the mulch mix.
- Never layer the coffee grounds pure in a thick layer.
- The fine particles, when they dry out, form a watertight barrier. Only heavy rains and day-long drizzles soften it enough that water will reach the ground underneath.
- Always add other materials like river sand, compost and regular garden soil to make a balanced mix.
- Alternatively, let the grounds dry. This makes them easy to sprinkle on the ground in a thin layer.
Additionally, excess traces of caffeine from the ground coffee might have detrimental effects on some plants. If there are too much coffee grounds in the soil, plants will grow slower or stunted until such a time that soil organisms are able to break the coffee down.
- This is especially true for seedlings, when only pure coffee grounds are used.
- Coffee grounds will not kill grown plants. It just takes time for them to recover in case of excess amounts.
Can You Water Plants With Leftover Coffee
If you have a little coffee leftover from your brew, you can use it to water your acid-loving houseplants like Dieffenbachia, African violets, and moth orchids. Only do this once a week to prevent making the soil too acidic.
It is a good idea to dilute the liquid coffee with water before using it for your house plants. Keep an eye out for signs of nutrient burn yellowing leaves or crispy leaf margins.

What About Potted Plants
If you dont have a garden but still want to make use of your grounds you are in luck! The same benefits and principles as above apply to indoor plants. You still need to keep the needs of the plant in mind.
If using fresh grounds make sure the plant likes acidic soil. Dont let the grounds form clumps or barriers that will prevent water from reaching the plant. For the most part, you wont have an issue if you compost it first.
Additionally, you will need to use a small number of coffee grounds per pot. Unless you have very large pots you will not need much.
Avoid Coffee Grounds For Some Plants
While gardens can benefit from coffee grounds, some plants aren’t known to thrive with them in the mix. Farming Method has a list of plants averse to it, including lavender, orchids, and pothos. In addition, studies have shown that broccoli, leeks, radish, viola, and sunflower also aren’t fans of coffee grounds, Constant Delights notes. Because caffeine inhibits the formation of roots in these plants , it’s best not to apply it near them.

Using Coffee Grounds Reduces Food Waste
Admittedly, coffee grounds arent the largest source of food waste. However, every little bit counts, and it all adds up. If youre already composting, then your coffee grounds and coffee filters can be composted, which means just a little less is going into the garbage every day. Using coffee grounds in your garden is an easy way to make your home and life slightly more sustainable.
Reducing food waste is good for the environment, but there are other ways to make a larger impact. The vast majority of food waste and pollution comes from large companies, not individuals. The best way to protect the planet is to let companies and legislators know that you care about the environment, either through letters, emails, or phone calls. This can be intimidating sometimes, but its much easier with friends or neighbors.
Consider looking for local environmental groups, or form one yourself. You can get together with your community members to write petitions or letters, clean up local streams or parks, start a community garden and brainstorm new ways to help your community accomplish its environmental goals. Of course, you can all compost your coffee grounds as well.

What Is A Cold Brew
Before we jump right into talking about grind sizes, lets take a second to recap what a cold brew is.
Cold brew is a type of cold coffee thats prepared by steeping coffee grounds in cold water instead of hot.
Because the coffee is made using cold water, you have to steep it for longer. Most baristas recommend steeping cold brew for between 16 and 18 hours.
The longer extraction time results in a smooth, rich coffee.
On top of that, the cold extraction method pulls more flavor and caffeine out of the beans compared to hot coffee. That makes for a perfect pick-me-up on a sleepy afternoon!
Cold brew has been around since the 1600s, but in recent years, it really become popular. Today, youll have no problem finding it in just about any coffee shop you walk into!

Coffee Ground In Compost
Throwing spent coffee grounds into your compost pile is all it takes to compost coffee grounds. Coffee filters that have been used can also be composted.
Coffee grounds should be composted. Compost material is divided into two categories: brown and green. Although your coffee grounds are brown in color, they are classified as green material in compost jargon, which means they are high in nitrogen.
The nitrogen content of coffee grinds is around 1.45%. Food scraps and grass clippings are two more green compost components.
Green compost material is made by mixing coffee grinds and old paper coffee filters into your compost. It must, however, be supplemented with brown compost material, such as dry leaves and newspapers.
You should use brown compost material in a 4-to-1 ratio with green compost material. If your compost pile has too much green material, it will begin to stink. The compost pile will not heat up if you dont have enough.
