It's not viewed as glamorous; saving your organic garbage, and maybe even some think it's 'bad', as a nasty way to attract critters! But saving your coffee grounds, egg shells and left over veggie scraps, is the way to healthier soil.
It's big business, making soil, and if you can improve yours for free, with your scraps and coffee grounds...well why not?
Not a coffee drinker, ask a neighbor for theirs, a restaurant; or use tea bags?
A bucket or pail works nicely as a receptacle (preferable with a lid), and a spot away from the path of activity, for your collection spot, is a good idea. If you have lawn refuse, (grass clippings and leaves) wonderful..add them! Citrus peels will draw butterflies and bees, but have no fear, they will focus on the fruit scraps. A viewing vantage point, indoors, may give hours of nature observations; as the cycle of life goes on in your yard!
It doesn't take long to break down and return to a soil consistency...and a science project! Kids will love finding worms and creatures, that both benefit and help create, the new soil. Birds and squirrels will also enjoy the free banquet, and will not hurt the process one bit.
If your not a gardener, this can also become a worm bed, for a fishing hobbyist, or a place to feed the birds, or just a recycling project; reducing your carbon foot print. Shredded paper, cardboard, and junk mail will all break down, if you decide to really throw your heart & spirit into it!
As the pile accumulates, dig out the bottom layers that have turned to soil. Some instructions say to turn the pile occasionally and maybe water it, but for the most part you just keep adding to it! and subsequently...use it! You will love the results so much; you'll be looking for other stuff to compost!
