Coffee grounds help to improve the texture and quality of the garden soil in several ways. Firstly, they act as a natural fertilizer, providing essential nutrients to plants. Secondly, coffee grounds improve the soil structure, making it more porous and allowing for better water retention. This is especially important in areas with dry or sandy soil. Lastly, coffee grounds increase the soil's acidity level, which is beneficial for acid-loving plants like blueberries, azaleas, and rhododendrons.

There are several ways to use coffee grounds in the garden soil. One way is to mix the coffee grounds with the soil in the planting hole when you are planting new plants. This will provide the plants with essential nutrients and improve the soil structure. Another way is to use coffee grounds as a mulch around the plants. This will help to retain moisture in the soil, suppress weed growth and provide the plants with nutrients as the coffee grounds break down over time. However, it is important not to use too much coffee grounds as it can make the soil too acidic.
What plants benefit from coffee grounds?
