Can you put too much coffee grounds in your garden?
Coffee grounds are acidic, so they should be reserved for plants that like acid. Coffee grounds could stunt the plant’s ability to use nitrogen if the soil is already high.
“If you have a lot of nitrogen in the soil, you’re not going to be able to take advantage of the nitrogen that you do have, and that’s what we’re seeing with coffee plants,” said Dr. Michael J. O’Connor, a plant physiologist at the University of Illinois at Urbana-Champaign, who was not involved with the new study.
How much coffee grounds should I add to my soil?

Which plants do not like coffee grounds?

Do coffee grounds attract rats?
Rats and mice are not interested in the smell or taste of coffee grounds. Coffee grounds that are fresh and used repel mice and rats. The researchers also found that the odor of freshly ground coffee was more attractive to rats than coffee ground that had been ground for a longer period of time.

These compounds are known to be carcinogenic and have been linked to a number of health problems, including cancer, diabetes, heart disease, and even Alzheimer’s disease.

If you don’t have a large compost heap, you may be able to use the grounds to add a little bit of nitrogen and phosphorus to a larger pile of organic matter. Mixing the ground coffee with your organic compost will help to increase the amount of nutrients that are available for your plants to take advantage of.
