Most Oregonians are familiar with the plethora of countertop compost collectors and yard debris rollcarts that have now become companions to our garbage and recycling bins. Composting is not a new idea brought about in recent years by environmentalists, however, it’s an age-old method of turning would-be waste into nutrient rich mulch. Mesopotamian clay tablets from as far back as 2120 BC mention composting, so it’s definitely not a new concept! So, what is composting and how can you employ these historic practices in modern times?
Composting is the act of taking organic matter—leaves, grass, flowers, fruit and vegetable scraps, eggshells, coffee grounds, even paper towels and pizza boxes—and letting them naturally decompose. Worm Bins have slightly different requirements regarding what you can add, but can be maintained in a smaller area, even inside the home and share the same idea.
Backyard Compost Bins can be purchased or made from wood pallets, or a simple wire structure. They don’t have to be complicated. Toss in anything from your gardening escapades: leaves, grass clippings, old pumpkins, remnants of flower and vegetable gardens, as well as the collected bits from your kitchen.
Apartment Dwellers, Don’t Despair. Worm Bins are here!
A worm bin can do the composting for you in a relatively small space. There are various types of worm bins you can purchase online, or you can make you own using a plastic tub with drilled holes for air circulation. In three to six months, the worms will have magically created a bin of rich castings (worm poop) as a soil amendment you can add to the top of your houseplants, or mix with potting soil to use as a planting medium.
With so many options available, from streetside composting and backyard compost piles to various worm bin contraptions, there is an easy mode of composting for everyone. Save space in the landfills and make your own homemade, nutrient-dense soil amendment! It’s simple, it’s easy, and as Martha Stewart says, “It’s a good thing.”
