COFFEE

Instead of disposing of the leftover coffee grounds in the household waste, you can use them as fertilizer for garden plants. The high content of organically bound nitrogen and other minerals such as potassium and phosphorus are excellent for promoting plant development. Coffee has a slightly acidic pH, making it ideal for fertilizing hydrangeas, rhododendrons, blueberries and other plants that love acidic, humus-rich soil.

However, indoor plants should not be fertilized with coffee grounds, as they will not be completely decomposed and will begin to mold. Instead, cold coffee diluted with water is suitable for pouring.
