Fertilizing with coffee grounds?

Simply work the coffee grounds into the soil and spread them well. Incorporate coffee grounds especially for acid-tolerant plants such as hydrangeas, rhododendrons, and blueberries. These plants like the slightly acidic pH value of coffee grounds. In addition, it contains important nutrients such as nitrogen, potassium, and phosphorus, which promote flowering and fruit ripening. Many sources on the internet indicate that coffee grounds are also good for earthworms. However, these statements are unconfirmed and, due to the caffeine content, rather unlikely. After all, coffee grounds still contain about half of the original caffeine. Coffee grounds decompose slowly and gradually release the nutrients, which makes additional fertilization with coffee grounds unnecessary. Remember to dry the coffee grounds well before spreading them to prevent mold growth.

Coffee grounds are an excellent fertilizer for garden plants. They can be used directly after brewing. Apply small amounts of coffee grounds to the soil or mix the cooled coffee into the watering water. Especially garden plants like blackberries and currants like a slightly acidic pH value and benefit from fertilization with coffee grounds. The humic acids contained in coffee grounds improve soil structure and promote flowering. Using coffee grounds as a natural fertilizer is a cost-effective and environmentally friendly alternative to commercial fertilizers. Coffee grounds in the garden are also a good plant protection agent, as slugs do not like caffeine.
