What Are The Benefits Of Using Coffee Grounds?

Coffee Grounds vs. Manure

Instead of using manure, coffee grounds have become a more nutritious source of nutrients for plants. Using coffee grounds for plants and garden soil eliminates the risk of increase of pathogens entering the soil.  They help kill diseases living in the seeds and roots of the plants, keeping them healthy for growth.  At the same time, it is economically friendly as purchases of chemically based fertilizers are minimized. It is also environmentally friendly since you help the trash going into landfills where they are only left to rot and put to waste.

Nitrogen, Calcium and Magnesium

Coffee grounds are a good source of nitrogen, calcium and magnesium that are greatly beneficial for the growth of plants. These are also beneficial for compost piles. Coffee helps maintain the balance of nitrogen which is helpful in decomposition of organic materials. Nitrogen is also very valuable for the fast-growth of vegetables.


Earthworms love to feed on coffee grounds. They are attracted to them. So as they feed and move into the soil, they help spread the nutrients and fertilize the plants. They also aerate the soil, inviting more oxygen for the roots.

Snail and Slug Killer

The caffeine and acid present in coffee grounds were proven to be fatal on slugs and snails that infest the plants. Spreading or spraying coffee on the soil around the plants would prevent slugs and snails from attacking them.


The grounds help increase the acidity of the soil which is helpful for the growth of acid loving garden plants.  However, it must not be used for non-acid loving plants for it may kill them.

Improves the Soil

Coffee grounds make the soil easier to till, thus it is easy to put nutrients and also easy for the plants to absorb them.

Other benefits:

  • Coffee grounds are free
  • They keep moisture
  • They are easy to store
  • They smell good compared to other natural and organic garden compost/fertilizer

So if you want to start your coffee ground nourished garden, head off to the nearest coffee shop. They would gladly give you as much coffee ground your garden can hold and start nourishing your plants to be healthier in an organic and safe way.

  4. Starbucks has a program called “Grounds for your Garden”. By going into your local Starbucks (no purchase necessary), you can just ask the barista behind the counter if they have any grounds to give you. They will typically have anywhere from 5-10 lbs to share. Although this time of year, they are often being requested more often.


    • Hi Karen, thanks for stopping by the site. Starbucks are well known for this practice and are one of the few chains to be involved in handing out their spent grounds. I built this site as a reference point for everyone with an interest in reusing grounds and it is great to see you here. Would love to see some of the other big players do the same under the Ground to Ground brand.
