Coffee grounds are an excellent nitrogen source, one of the essential nutrients for healthy and robust plant growth, along with potassium and phosphorus. Also contain magnesium, copper, calcium, zinc, and other trace minerals.
Coffee is acidic, which means that when you add coffee grounds to the soil of your houseplants, it lowers the soil’s pH level. Like most plants, Pothos like to have a soil pH that is slightly acidic and sits between 6.0 and 6.5².
