Why use coffee grounds?
Coffee grounds are rich in nitrogen, potassium, phosphorus, and other micronutrients that are extremely valuable for plants. Due to their caffeine content and structure, they can effectively repel pests such as slugs and ants. Grounds help improve soil structure by increasing its water and air permeability, which positively affects plant growth.
Nutritional content of grounds
Coffee grounds contain macronutrients such as magnesium, copper, and zinc, as well as micronutrients. Their intense odor and structure repel pests, discouraging them from approaching our plants.
How to prepare coffee grounds for garden use?
The first step to using coffee grounds in the garden is collecting them. After enjoying your morning cup of coffee, set the grounds aside in a container instead of throwing them away. The collected grounds can be stored for several days before being used in the garden.
Drying the grounds
Coffee grounds should be properly dried to be ready for garden use. They can be spread on newspaper or paper towels and left in a warm, airy place for a few days. Drying the grounds prevents mold formation and facilitates later storage.
Using coffee grounds in the garden
Coffee grounds are a natural way to effectively deter slugs. The texture of the grounds makes it difficult for slugs to move across the soil. Simply sprinkle the grounds around plants that are prone to attacks by these pests. This should be done regularly, especially after rain, which washes the grounds away. This way, we can effectively protect our plants from destruction.
Similarly, coffee grounds also repel ants. The intense aroma of coffee effectively discourages these insects from visiting our garden. To keep ants away from plants, simply sprinkle the grounds in areas where the insects are most active. You can also mix the grounds with borax to further enhance their effectiveness in battling these pests.
Using coffee grounds to water potted plants
Coffee grounds can be an effective fertilizer for both garden and potted plants.
For potted plants, it is recommended to use a smaller amount of ingredients. Simply add one to two teaspoons of grounds to a cup of water. Mix it well and use it to water the plants in the pots. This proportion of ingredients is suitable for smaller plants and helps avoid over-fertilization.
Which plants to water with the grounds solution?
The nutrient solution from the grounds is excellent for plants that like acidic soil. For potted plants, the grounds solution can be used for peace lilies, cacti, anthuriums, or Stephanotis, for example.
For garden plants, you can use the grounds fertilizer on hydrangeas, rhododendrons, blueberries, and azaleas.
Before using coffee grounds, it's worth checking what type of soil your plants prefer.
