People who are thinking of creating their own compost heap may consider using worms. But is that a good choice or a waste of time? When thinking about how to compost, you have to consider nature's little friends. They are helpful, but mean you have to consider a few extra factors in creating your compost heap.
When considering using worms for composting, you need to consider that you must build a bin for your worms. This bin should be a wooden box, metal tub, or plastic basin, as they each allow for proper and necessary air circulation. You want a shallow bin, no more than 18 inches deep, since the worms eat near the surface and a deeper bin will result in unwanted foul odours.
To figure out the size of the bin needed, measure your kitchen scraps for a couple of weeks. Allow one square foot of space for every one pound of scrap materials per week. It is recommended to estimate a little larger rather than too small as you don't want to crowd the bin. Before using your bin, always scrub a new bin with detergent and rinse with hot water before you use it. If you are building a wooden bin, do not use pretreated woods. They are harmful to the worms and could contaminate your compost. Make sure your worm bin has 9-15 holes drilled in the bottom to allow for air circulation as well as letting the compost drain of excess moisture. Keep the bin somewhere relatively cool, such as a basement or alley beside your house, as worms do not like hot living conditions.
So far all you have considered in your efforts to living off the grid is the compost bin for your worms to live in. But another consideration is the bedding you need for the bin. Bedding holds moisture in the bin. Your bedding materials should be biodegradable and free from chemicals and pesticides. Some suggestions are shredded newsprint or computer paper, shredded cardboard, leaves, peat moss, or crushed eggshells. Having a good mix of paper and natural materials, like the eggshells, will help your compost to work faster.
So what kind of worms should you use? Is it as easy as digging up worms in your backyard? Yes, and no. You'll want to get redworms. They are capable of reproducing quickly in captivity and are quick to break down materials into usable compost. How many worms do you need? Approximately two pounds of worms is estimated for every one pound of daily scraps. There are about 1000 worms per pound. About one pound of worms is sufficient for a 2 foot by 2 foot bin. If you're worried about the worms reproducing and crowding the bin, that shouldn't be a concern. The population will level itself out and sustain a number that can be sustained based on the amount of food available and the amount of space.
So are worms necessary to composting? No. Is it a better way to go when starting a compost? That is up to you, and if you want nature's little helpers to give you a helping hand in becoming more Eco-friendly.
