Another Reason To Love Starbucks

Look what I got yesterday for free at Starbucks!  The whole bag went directly into my compost pile, soon to be applied to my garden.

In compost jargon, coffee grounds are a “green,” meaning an item that is rich in nitrogen.  They’re like grass clippings, not leaves or biochar.

Coffee grounds are approximately 1.45% nitrogen. They also contain magnesium, calcium, potassium, and other trace minerals.

There are several ways you can put used coffee grounds to work in your garden:

  • Put coffee grounds in your compost bin. As noted above, they are a valuable source of nitrogen.
  • Add grounds directly to the soil in your garden. You can scratch it into the top couple inches of soil, or just sprinkle the grounds on top and leave it alone.
  • Create a slug and snail barrier. Coffee grounds are both abrasive and acidic, so a barrier of grounds placed near slug-prone plants may just save them from these garden pests.
  • Make coffee ground “tea.” Add two cups of used coffee grounds to a five-gallon bucket of water. Let the “tea” steep for a few hours or overnight. You can use this concoction as a liquid fertilizer for garden and container plants. It also makes a great foliar feed.
  • Add coffee grounds to your worm bin. Worms love coffee grounds! Add some to your worm bin every week or so. Just don’t add too many at once, because the acidity could bother your worms. A cup or so of grounds per week for a small worm bin is perfect.

I’m going back to Starbucks tomorrow for more free grounds.  I drink tea…

  1. I love the free grounds too! Though I can only use them in the raised beds because the dogs also love them and will stop at nothing to dig up every last coffee-ground morsel. Then proceed to have the jitters all day. 🙂

    I’ll try that this summer when I do my windowsill box herb garden!

    There should be a prize for the best tip of the month because this is it.
    Nothing like really useful free stuff.

  4. What a lovely idea – and I do love Starbucks but only drink their teas! My friend’s mum uses fresh coffee grounds to exfoliate her hands because it leaves them incredibly soft and white! 🙂
