How to Reuse Coffee Grounds in the Garden 

  • Sprinkle used grounds around plants before rain or watering, for slow-release nitrogen.
  • Add to compost piles to increase nitrogen balance. Coffee filters and tea bags break down rapidly during composting.
  • Dilute with water for a gentle, fast-acting liquid fertilizer. Use about a half-pound can of wet grounds in a five-gallon bucket of water; let sit outdoors to achieve ambient temperature.
  • Mix into soil for houseplants or new vegetable beds.
  • Encircle the base of the plant with a coffee and eggshell barrier to repel pests
Most Starbucks have a little box in their store that says “for your garden”.   If it is empty I am sure you can ask the Barista for some.

If you enjoy iced coffee, why not freeze the extra coffee in ice cube containers and use in your next iced coffee or blended drink.  No more watered down iced coffee.  It is the perfect solution if you use the same type of coffee for your cold drinks.

Water your plants

Dilute the coffee with water, I do it right in the coffee pot itself and give my houseplants a splash of caffeine.

Use in Chocolate Cakes

There is nothing better than coffee and chocolate.  I love adding coffee in place of the water needed in chocolate cake recipes.   If the chocolate cake recipe calls for hot water, simply reheat the coffee in the microwave and add it to the batter.
