Worm excretion, also known as Vermiculture, is an excellent way to fertilize your garden organically. Listed below is a step by step guide to get you started on creating your own worm compost fertilizer.

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.

Have Plenty of Holes in 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.

Save 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.

Buy 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.

Cover the Container

Worms like it dark and moist, so cover with a wooden board when outside. This will also keep away predators. Inside, heavy plastic will do.

Collect Worm Excretions

Within four to six weeks from starting your worm compost you will start to notice the bedding becoming darker. Finally, in about two to three months, there will be very little of your original bedding remaining. If you wish to collect all of the compost or castings at once, simply pour the container onto a tarp or old shower curtain liner. The next step is to shine a light over the piles to ensure the worms move to the bottom. Once you are sure they are at the bottom, begin scooping the castings until all that is left are the worms. Place new bedding, the worms and some of the castings back in your container and start all over again.
