Tips on how to Make a Worm Compost System

Tips

 * Egg shells in your bin increase the calcium content of the compost you produce. Worms also seem to like to curl up in them. To be most effective, eggshells must be dried out and finely ground (with a mortar and pestle or a rolling pin) before their addition to a bin. Use raw eggshells, not cooked.
 * You can throw your coffee grounds, unbleached filters, and used teabags (remember to remove the staple!) right in the bin.
 * Calcium carbonate works well to solve most problems. Be sure to use calcium carbonate (e.g., powdered limestone) and not quicklime (calcium oxide).
 * Green food increases nitrogen in your finished compost. Examples are: green grass, beet tops, carrot tops, philodendron leaves, fresh cut clover or alfalfa.
 * Remember that a worm bin is a tiny ecosystem. Don't attempt to remove the other critters living in your worm bin, they are helpers. However, do remove centipedes: Centipedes are carnivores, and eat baby worms and worm eggs.
 * If you would like to collect the water (liquid fertilizer) produced by watering your worms, place a tray under the compost bin. Otherwise, the ground under the bin will become terrifically fertile. An elevated bin (either on bricks, or a bin with built-in legs) sitting in a tray of water will also prevent ants and other unwanted critters from getting into the bin.
 * Brown food increases carbon and phosphate in your finished product. Examples are: paper, cardboard, wood chips, leaves, bread.  If adding fresh lawn grass, be certain chemicals have not been added to the lawn.  Lawn chemicals are deadly to the ecosystem in the bin.
 * Shredded paper, egg cartons, cereal boxes, and pizza boxes all make excellent bedding (avoid glossy paper). Always soak household paper waste bedding for at least 12 hours before adding it to the bin, and thoroughly squeeze out the water first.  Don't shred junk mail envelopes unless you remove the plastic windows!  Worms won't eat plastic, and picking hundreds of shredded plastic window panes out of otherwise beautiful compost is a vermiculturist's nightmare.
 * Finely ground and moistened grains (flour, oatmeal, etc.) are eaten the fastest, followed by fruits, grass, leaves, cardboard, paperboard (cereal boxes), white paper, cotton products, and magazines (slick paper). Wood takes the longest (up to a year or more).
 * If you have two bins, it can be a bit easier to get at your compost. Fill one bin and start the next. When you want to get at the compost, move the un-composted matter from bin one to bin two and use all the finished compost. Bin two, the now-active bin, becomes full and then bin one becomes the active bin again.
 * Pre-composted cow manure is a great food for worms. Just be sure to bury it at least 3 inches deep. Look at the warnings before you start adding any type of manure.
 * A balanced diet makes for a healthy bin, healthy worms and a great finished product.
 * You can add teabags.
