- Pest Deterrent: The caffeine and other compounds in coffee grounds can deter pests like slugs and ants.
- Cost-effective: This is a way to recycle waste from your kitchen, reducing the need for commercial fertilizers and pesticides.
Ingredients:
- 2 cups of used, dried coffee grounds
- 5 gallons of water
- Optional: 1 teaspoon of liquid soap (helps the spray adhere to plants)
Tools:
- Large bucket or container (5-gallon capacity)
- Measuring cup
- Stirrer or long spoon
- Cheesecloth or fine mesh strainer
- Spray bottle or garden sprayer
- Funnel
How to Prepare:
You don’t need much preparation to use coffee grounds. Simply collect the used coffee grounds and allow them to dry to prevent mold growth. You can then directly add these to the soil or compost bin, or make a liquid fertilizer.
How to Use:
- Direct Application: Scatter dried coffee grounds around the base of plants that require a nitrogen boost. Gently mix them into the top layer of soil using a spade or your hands.
- Coffee Ground “Tea”: For a liquid fertilizer, add 2 cups of dried coffee grounds to a 5-gallon bucket of water. Let it sit for a few hours or overnight. Strain and use the liquid to water plants in need of a nutrient boost.
- Compost: Incorporate coffee grounds into your compost pile, where they’ll contribute valuable nutrients as they break down.
- Pest Control: Sprinkle a barrier of coffee grounds around plants to deter pests like slugs and ants. However, this method is not foolproof and should be part of a larger pest control strategy.
- Mulch: Used coffee grounds can be mixed with other organic matter to create a nutritious mulch.
Precautions:
- Acidity: Coffee grounds are generally acidic and can lower the soil’s PH. Use them carefully around plants that prefer alkaline soil.
- Overuse: Too much of a good thing can be harmful. Excessive use of coffee grounds can lead to nitrogen toxicity.
- Mold: Wet coffee grounds can develop mold. Always dry them out before storing or using them.
- Caffeine Sensitivity: Some plants are sensitive to caffeine, which can inhibit their growth. Use cautiously until you see how your plants react.
Using coffee grounds in your garden is a smart and sustainable practice that not only reduces kitchen waste but also enriches your soil, boosts your plants, and aids in pest control. However, it’s essential to use them thoughtfully and observe how your plants react to this treatment.

- Frequency: For preventive measures, you can apply this spray once every two weeks. For active infections, apply once a week.
Precautions:
- Plant Sensitivity: Not all plants react well to baking soda. Always do a patch test first.
- Sunlight: Apply the spray during the cooler parts of the day (early morning or late afternoon) to minimize the risk of sunburn on leaves.
