Story summary
- Coffee grounds provide nitrogen and improve soil texture, but must be used cautiously.
- Some gardeners sprinkle used grounds on pots to deter pests, but this can cause problems.
- Used grounds are slightly acidic and can compact if applied too thickly, causing water pooling and root suffocation.
- One should limit to 10% dried coffee grounds in compost or outdoor soil and avoid using them as a standalone fertilizer.
