What is coffee water and how is it made?
Coffee water is a nutrient-rich solution made from brewed coffee that can be used to nourish plants. It primarily contains beneficial nitrogen compounds, potassium, and various trace minerals that can enhance plant growth and improve soil health. The process of making coffee water is simple: you brew a pot of coffee using your usual method, then dilute the leftover coffee with water to achieve an appropriate concentration for your plants.
To make effective coffee water, aim for a ratio of one part brewed coffee to three parts water. This dilution reduces the acidity of the coffee, making it safer for most plants to absorb. Once you have mixed the solution, allow it to cool before applying it to your plants, ensuring they are not shocked by the sudden introduction of a new substance.
Which plants benefit most from coffee water?
Coffee water is particularly beneficial for acid-loving plants, such as blueberries, tomatoes, and roses. These plants thrive in a slightly acidic environment, which coffee can help provide.
