Coffee is a staple in many households, and as a result, there is often a lot of coffee grounds left over. But what do you do with all of those leftover coffee grounds? Many people choose to use them in their gardens as fertilizer, but is this a good idea?
“The Pros of Using Coffee Grounds for Plants”

- Acidity: Coffee grounds are acidic, which can be beneficial for plants that prefer a more acidic soil, such as blueberries and roses.
- Organic matter: Coffee grounds add organic matter to the soil, improving its structure and water-holding capacity.
“The Cons of Using Coffee Grounds for Plants”
- Salts: Coffee grounds can contain salts, which can build up in the soil over time and become toxic to plants.
- Mold: Wet coffee grounds can attract mold, which can be harmful to plants.
- Caffeine: While caffeine is not toxic to plants in small quantities, it can be harmful if used in large amounts.
