As many of you are no doubt aware, but others may not be, coffee grounds are a good addition to your compost, or even applied directly to your garden. Although coffee beans are acidic, most of this is lost during the brewing process, and the used coffee grounds are very good for your soil. Having read that some time ago, I have begun dumping my used coffee grounds (I even break them open and shake it out of the K-cups so that it doesn't go to waste) into some cat litter containers that I have been using for planting. Prior to that, I had simply been adding it to the stuff that goes onto the compost pile but, mixed in with all the other stuff, it's impossible to determine what works and what doesn't. This spring, I found weeds growing very well in the containers that I had been adding coffee grounds to, and they were growing directly in the largely uncomposted coffee grounds themselves, since composting slows considerably outdoors in a Maine winter. I added coffee ground directly to the soil around some beans and some other plants that I planted this spring and the side of the bean garden that included coffee grounds is growing noticeably faster than the side without coffee grounds. So don't let your coffee grounds go to waste.
