Coffee grounds can be used as fertilizer. They contain a large amount of nitrides, which are beneficial for the growth of plant leaves and are particularly suitable for acid-loving plants, such as azaleas, hydrangeas, gardenias, Coleus blumei, Tradescantia zebrina, ferns, and orchids, which are all suitable for using coffee grounds as fertilizer.
Using coffee grounds as fertilizer
Coffee powder can be used as fertilizer for plants, but it cannot be applied directly. It needs to undergo fermentation and decomposition. Coffee powder contains about 2% nitrogen, which can transform organic matter into fertilizer to provide nutrients, having the effect of improving plant soil and supplementing acidic nutrients.
Coffee powder can be used as flower fertilizer, suitable for plants that like nitrogenous substances and most annual plants and onion plants. Sprinkling coffee powder in the flowerpots of acid-loving plants at home, such as azaleas, roses, and camellias, can help them bloom more beautiful and vibrant flowers.
How to make fertilizer from coffee grounds
1. Dry composting
Place the coffee powder on the balcony and stir it every day. After about 10 days, the potted plants can be placed in it.
2. Wet composting
Place the coffee powder on the balcony, prevent it from molding, and do not stir it over. After a few days, you will know it has molded. Stir it with sand and then put it in the potted plants.
3. Bagging
