How Do Coffee Grounds Change the pH Level of Your Soil?

When coffee grounds are used as fertilizer, they will absorb water from the soil and release it slowly to the plant’s roots. This will increase the absorption of nutrients and water by the plants. It also helps in the improvement of soil quality. Coffee grounds will make the soil less acidic and increase the pH level.

Can coffee grounds acidify your soil?

In acidic soils, the high pH of coffee will keep the soil from having a neutral pH balance. That can be good or bad, depending on what is growing there. A soil pH of 2.5 is ideal for most crops. But a soil pH of 3.5 is ideal for orchids. If your soil has a pH level of over 4.0, adding coffee grounds will lower the pH.

Can coffee harm plants?

Although coffee beans are rich in nitrogen, they are also very acidic and contain compounds that can leach into the soil, potentially causing nitrogen deficiency in plants.

In large quantities, it may affect plants, possibly inhibiting root development. Coffee grounds should never be used alone in soil or compost; the soil or compost should be tested before any planting.


Coffee grounds can be used as fertilizer if they’re adequately composted. However, if the grounds are placed directly on the plant, they can cause root damage. The best way to use coffee grounds is to put them in a container with holes. The roots will be able to soak up the nutrients from the coffee grounds, and the excess water will drain away. This way, the plant can still absorb the nutrients, but there will be less chance that the roots will be damaged.
