Coffee grounds contain substantial nitrogen and potassium, both important for plant growth. They also includes many other trace minerals and carbohydrates. This also makes it a good fertilizer.
But since coffee grounds lack phosphorus (used in plant food for flowering plants) it is better for use on non-flowering shrubs, foliage plants and grass than flowers.
For "casual" use, let them dry first (otherwise they can develop mold and that's not helpful for plants) and then work them lightly into the soil.
If you compost, just dump them into your regular compost bin; they have a carbon-to-nitrogen ratio of 20:1, about the same as grass clippings. After used to make coffee, grounds contain up to 2% nitrogen. They are acidic with a pH of between 3.0 and 5.0, making them perfect for mulching rhododendrons, azalea and other acid loving plants.

∙ 14y agoYes, coffee beans has high nitrogen content which usually is scarce in soil. So plants will benefit from this fertilizer. I save all the used coffee beans to use it. You have to let it dry inside/outside (depends on how humid your place is) and just save it in pile so you can use it later.

Can coffee grounds be used to fertilize plants?
Coffee grounds can be used as compost material, fertilizer, or mulch. So they can be applied to the surface, or mixed with the below ground soil. Compost used as fertilizer tends to be applied at the rate of 1/4 inch. Compost used as mulch tends to be mounded to a level of 2-3 inches. But in not any of the three cases should the compmost, fertilizer, or mulch be only of coffee grounds. For the grounds are acidic. So they can be used to slowly, slowly change the soil pH. And they can be sprinkled around such acidic soil lovers as azaleas, blueberries, and evergreens. They should not be sprinkled around alkaline soil lovers such as lupines.

One way to keep cats out of your garden is the following: Every time you make a pot of coffee, set aside the used coffee grounds until they are dried out (you can continuously use a plastic container specifically for thisa purpose). One the used coffee grounds are dried out, take them out to your garden and spread/sprinkle them in and around the area where you don't want cats going. The extra benefit of this is that the used coffee grounds have certain nitrates in them that plants love and therefore they are a good fertilizer as well.
