There are a number of ways to use up those old coffee grounds, right outside your door.
Time Required: n/a
- Great for compost. Coffee grounds add great texture and acidity to your compost. Tea bags work well too.
- Fertilizer. If you don't have a compost bin or pile, you can just add some grounds directly to the soil around your flowers for some extra fertilizer.
- Control some bugs. Supposedly, ants hate coffee. So spread your old grounds around where you have ant problems.
- If you don't brew enough coffee for a good supply of grounds, ask at your local coffee shop. Many will be happy to save some for you.
