4. Compost
Add the coffee grounds to your compost pile along with other food waste. The grounds are said to contain generous amounts of magnesium, potassium, phosphorus, and copper. All these nutrients can help in the successful growth of your plants. Moreover, if you hate the smell of your compost, then add grounds to the mixture. The coffee will aerate the mixture and will mop up the extra moisture, thereby, keeping the foul smell away.
