How much coffee grounds do you use for indoor plants?

* Acidity: Coffee grounds are acidic, and many indoor plants prefer neutral to slightly alkaline soil. Applying too much can lower the pH, potentially leading to nutrient deficiencies and stunted growth.

* Nutrient imbalance: While coffee grounds contain some nitrogen, they also have high levels of phosphorus, which can disrupt the plant's ability to absorb other vital nutrients.

* Mold and pests: Damp coffee grounds can attract mold and pests, creating an unfavorable environment for your plants.

* Blocking drainage: Too many coffee grounds can compact the soil, hindering proper drainage and leading to root rot.

Instead of directly applying coffee grounds, try these alternatives:

* Composting: Add coffee grounds to your compost bin, where they will break down and contribute to a balanced and nutrient-rich compost.

* Diluted coffee: Make a weak coffee brew and use it as a plant fertilizer.

* Coffee grounds tea: Steep coffee grounds in water for a few days, then use the resulting tea as a liquid fertilizer.

Remember: Always test your soil pH before adding anything to it. Start with small amounts and observe your plants' reactions. If you notice any negative effects, adjust accordingly.
