The Science Behind Coffee Grounds and Soil pH

Coffee grounds have a significant impact on soil pH, making them an ideal amendment for gardeners looking to create a more acidic environment for their plants. But what exactly happens when coffee grounds are added to the soil, and how do they affect soil pH?

Soil pH is a measure of the concentration of hydrogen ions in the soil, with a lower pH indicating a more acidic environment. Coffee grounds have a pH of around 6.5-7.0, which is slightly acidic. When added to the soil, the coffee grounds begin to break down, releasing their acidic compounds and lowering the soil pH.

The main culprit behind the acidic properties of coffee grounds is a compound called citric acid. Citric acid is a natural preservative that is found in high concentrations in coffee beans. When coffee grounds are added to the soil, the citric acid is released, helping to lower the soil pH and create a more acidic environment.

But how much of an impact do coffee grounds really have on soil pH? Research has shown that adding coffee grounds to the soil can lower the pH by as much as 1-2 units, depending on the amount of coffee grounds used and the initial pH of the soil. This can be especially beneficial for plants that thrive in acidic environments, such as azaleas, blueberries, and rhododendrons.

It’s worth noting that the impact of coffee grounds on soil pH can vary depending on the type of coffee grounds used. Fresh coffee grounds, for example, tend to be more acidic than stale or old grounds. Additionally, the pH of the coffee grounds can also be affected by the type of coffee beans used and the roasting process.
