Worm Composting Bin
by John Yazo
Choosing the proper bin for worm composting is a very important. There are a few choices that you have to make. How much material you will be composting, where you are going to be doing your composting and will you have to physically move the bin from time to time.
Worm composting bins can be purchased from local garden centers and from online suppliers or you can make one yourself. They can be made out of plastic or wood. Wood bins are better because of the woods ability to breath and allow better aeration to the composting process. Plastic containers tend to keep the compost wetter which leave the chance for the compost to leave a more unpleasant odor. Whatever you choose for a bin make sure there are holes in the bottom of the container to allow for drainage. The holes should be spaced about 8" to 10" apart and 1/4" to 1/2" in diameter. If you decide to build your own bin don't use treated lumber.
Other items that can be used as a bin for composting are old dresser draws, wooden barrels or even an old chest. Try not to use any items that are to large or heavy to lift when full. You may need to move the bin from time to time depending on the weather conditions in your area.
After you have decided on what you are going to use check to see if there are sufficient hole in the bottom for drainage, if not drill them before yo start filling the bin.You don't want large holes in the bottom that the compost is going to fall through, place 1/4" by 1/4" screen over any existing large holes if needed. Drainage is very important in a compost bin for worms.
The last part that you will need to complete your compost bin is some type of cover. Depending on where you are going to locate the compost bin you can use anything from black plastic, burlap or a solid wood cover. If your plan is to compost outside a solid wood cover would be your best choice. When composting outside you want a cover that is going to keep rain water out to avoid soaking the compost and bedding material. The cover shouldn't be air tight, worms need ventilation.
