Why Coffee Grounds Work as Fertiliser?
Coffee grounds are a rich source of nitrogen, which is essential for leaf growth. They also contain trace minerals like magnesium and calcium, which are beneficial for plants. Plus, they help improve soil structure by enhancing its water retention and drainage.
How to Use Coffee Grounds---
-
Dry and Sprinkle: After you brew your coffee, let the grounds dry completely. Once dry, sprinkle a thin layer (no more than ½ inch) directly onto the soil of your houseplants.
-
Mix with Compost: Mix used coffee grounds with your compost. This adds nutrients to the compost and helps create rich, fertile soil for your plants.
-
Coffee Ground Tea: You can make a liquid fertiliser by soaking used coffee grounds in water for a day or two. Then, strain the grounds and use the “coffee tea” to water your plants.
Things to Keep in Mind---
- Moderation is key: Too many coffee grounds can make the soil too acidic, which isn’t ideal for most houseplants. Use them sparingly, especially for plants like succulents and cacti that prefer neutral or slightly alkaline soil.
- Rinse thoroughly: If you're unsure about the acidity, you can rinse the used grounds before applying to reduce their acidic content.
By reusing coffee grounds, you’re not only giving your plants a nutrient boost but also helping to reduce waste!
