Coffee Grounds as Fertilizer – How To Use It For Plants

Jul 5, 2021 Garden by jolie

Normally, coffee grounds end up in the trash, but… Did you know that they can help you to have healthy plants? They are a very effective fertilizer, so much so that it admits many ways to become natural food for both the garden and the pots.


Yes, coffee grounds are good for plants. We can use these traces of plant matter to make organic homemade manure in the composter, although it is also possible to add the remains of the coffee directly on the ground if the substrate is well drained.

In any case, coffee leftovers will help us fertilize our plants,which promotes the rootedness and development of the plant.


We can make an excellent liquid fertilizer with the coffee grounds and even with the remains of liquid coffee that have been left over from our breakfast. This type of habit can be carried out practically daily next to the watering of our garden or pots.

To make a liquid fertilizer with the coffee grounds it will be enough to let the remains stand in a bottle. We will let it sit a whole night and even two so that it absorbs better. Then we will always use it before watering, right near the base.


Coffee grounds are an ideal fertilizer for plants, since coffee seeds have essential nutrients such as nitrogen, phosphorus, potassium, calcium, magnesium and sulfur,which serve them to grow and have a perfect development.

Regardless of whether you decide to throw them into the compost or directly on the surface of the substrate, your plants will surely look healthier in less than you imagine 🙂.

Acidifies the earth

Soils or substrates that have a high pH, of more than 6, cause many problems to acidophilic plants such as Japanese maples, azaleas,or camellias. To avoid this, they should be planted on land whose pH is low, between 4 and 6.

However, sometimes it happens that we are in a season of the year in which it should not be transplanted, as in summer or winter. What to do? Throw coffee grounds on them. They will add acidity to the soil,so we will prevent the plants from looking tristones.

Serves as food for worms

Earthworms have a very bad reputation, but without them the plants that are in soil would have difficulty growing well, since they keep the soil aerated and, therefore, also the roots of the protagonists of the garden.

To make their lives easier, we can feed them coffee grounds. This way we will have better maintained plants.

Repels pests

While a garden must feed and protect a number of animals, including insects, the truth is that there are some that cause a lot of damage to plants, such as snails. These are molluscs that have a voracious hunger, and to relieve themselves they eat all the leaves they find in their path. But not only that, but they also feed on cacti.

Another pest that must be kept under control is that of ants. While they alone do not cause damage, they usually come when aphids are already attacking plants. To prevent all these animals from destroying our beloved flowers and orchard, it is highly recommended to throw coffee grounds around them to scare them away.
