Organic Gardening – How to Make Worm Compost Fertilizer
Vermiculture is the fancy word for worm excretion which is worm compost. Heres how to do your own worm composting.
Choose the Proper Container
You will need a container at least 8 to 12 inches deep. Wood is better as it absorbs moisture and insulates the worms. A rectangular plastic container is often used, but the compost tends to be soggy.
Aerate the bottom
Drill holes at least 2 inches apart all along the container bottom. Plastic containers may need more holes. Raise the bin off the ground with bricks. This provides air flow to the worms and prevents the materials from rotting. Keep a tray underneath the bin to catch excess moisture that can then be used for liquid fertilizer. If your compost comes out too wet, simply drill more holes.
Line with Newspaper
To line the bottom of the container, simply shred newspaper into one inch wide strips and spray with water from a spray bottle until damp. Once this is completed, you will need to add about one cup of sand to the container. The sand assists the worms with their digestion.
Collect Kitchen Scraps
Just as you would save leftovers for your home composting, you will need to save your kitchen scraps for your worm compost. This should be started at least one week prior to purchasing your worms. The best foods are egg shells, used tea bags, coffee grounds and raw fruit and vegetable leftovers. The foods you want to avoid are meat, bones, cheese, milk or mayonnaise and salad dressings.
Purchase Your Worms
Red worms or red wigglers are best in a compost bin because they thrive off of organic material like rotting vegetables. You will need two pounds of worms for one day each of food waste, this is around 2,000 worms.
Put a Cover on the Container
When placing your container outside, a wooden board works best as it keeps the worms in darkness just as they like it while keeping the soil moist. In addition, it also prevents predators from getting in. If your container is indoors, a simple plastic lid cover will suffice.
Collect Castings from Worms
After two to four weeks, the bedding in the container will start to appear darker. By two to three months, nothing of the original bedding will be left. At this point, you can then harvest your worm castings or compost. First, simply pour the container out in piles on a tarp or old shower curtain liner. Then, shine a bright light over the piles to ensure all the worms move to the bottom. Now you can begin collecting. Scoop away all the compost until all that is left are worms. Finally, re-line the container with new bedding, add worms and some of their castings and begin again.
