Many plants love coffee grounds, but have you ever wondered why?Well, it is because coffee grounds retain more moisture, contain the macronutrient nitrogen, repel pests...
If you’re in a hurry and need a quick nitrogen fix or pest-repellent for your plants, you can scatter the coffee grounds on the potting mix. You can also mulch your plants with coffee; just make sure they’re never dry, or else they’ll repel water.
Making a coffee fertilizer tea is one of the best ways to get nitrogen to your plants quickly. Liquids are generally absorbed faster than granules or grounds, which is why this fertilizer is an excellent solution to nitrogen deficiency.
Use Coffee Grounds To Make A Pest-Repellent. Mix two tablespoons of used coffee grounds with a cup of aromatic herbs, such as lavender, rosemary, sage, thyme, etc., and add two cups of water.
Another thing you can do with coffee grounds instead of throwing them away is compost them. They will enrich the compost with nitrogen and make it perfect for all plants that enjoy slightly acidic soil, such as roses, hydrangeas, rhododendrons, etc.
If you hate waste as much as we do, you can pour the leftover coffee into the pot or give it to your outdoor plants.
However, don’t do it every day, as it can make the soil too acidic, and your green friends won’t love that!
