This one is kind of fun: coffee as fertilizer.  Yep, coffee grounds (and tea grounds and tea bags for that matter) provide an excellent source of nitrogen for your indoor and outdoor plants, transplants, lawn, and vegetable gardens.  There are many ways to use it as well.  You can add coffee grounds directly to soil for a slow release effect, or mix them with a bucket of water prior to watering plants as a more fast acting fertilizer.  Coffee grounds can be mixed in with your composting material, as well as utilized for some if its pest deterrent qualities.  The rule of thumb out there is that plants that thrive in acidic soil generally prosper with this kind of additive.

What’s more, you can get coffee grounds from local restaurants and coffee shops to use at home.  Starbucks has made five pound bags of used grounds available to customers for free through its Grounds for Gardens program since 1995.  If you’re not close enough to a Starbucks (hard to imagine in the world today that anyone isn’t within a ten or fifteen minute drive) call around to your local Chesterton, Crown Point, or Hobart restaurants and ask if they save coffee grounds for their patrons’ use.
