The answer is yes, but only if you are going to use the grounds as a mulch. They are not good for composting or fertilizer.
Composting coffee grounds can lead to issues with the nitrogen content in your soil and even cause toxicity in plants. If you have a lot of coffee grounds, you should consider recycling them instead of composting them. You can use coffee grounds as mulch around your plants to keep weeds from growing and help prevent pests from infesting your garden. The coffee grounds also act as a natural fertilizer that will help feed your plants.
The amount of time it takes for coffee grounds to break down depends on the type of soil you have and how much moisture there is in the air. In general, it takes six months to one year for the coffee grounds to break down completely into nutrients that plants can use.
