Making a Worm Farm

The first step in making a worm farm is to gather all of your materials.
One of the main components is the bedding. Shredded paper is the most used material in the bedding. Also used in the bedding are eggshells, animal manure, peat moss and other organic matter; such as, dried plants, straw, grass, or other organic materials found around your house. Then you need to add two adult handfuls of soil to the bedding to give the worms roughage. Altogether the bedding should weigh 4-6 pounds.
The last step is to add the worms in the bedding.





Feeding and Caring for the Worms

If you want to keep the worms alive, you must feed and care for them.
The first thing to do is keep the bedding moist. The second thing to do is feed the worms. You should feed the worms vegetables, fruit and other non-meat organic waste products. You should not feed the worms dairy, meat, greasy/oily foods or tobacco. The worm’s favorite foods are pumpkin, watermelon, and cantaloupe. Caring and feeding the worms in this manner, makes the worms happy and they make a lot of vermicompost.





Starting the Process

A worm bin can be put wither indoors or outdoors. Indoors, you can place the worm bin almost anywhere, because it produces hardly any odor. If you would like to put the bin outside, you have to make sure it has shade in the summer, and shelter in the winter. A garage provides both, so that might be a good place to keep it.

After choosing its location, it is time to prepare the bedding. To do this, you must lay down a newspaper soaked in water in the bottom. The paper needs to be wet, but should not drip – then you have the right humidity. After this, you need to put the paper and the organic matter in the bin, so it is approximately 3/4 full. When this is done, you can gently put the worms in the bin. Remember that worms don’t like light, so if you leave the lid of the bin off, they will burrow deep into the bedding. After 1-2 hours, you can feed them.



To feed the worms, dig a small hole in the bedding, put the food in the hole, and cover the hole with one inch of bedding. The holes should be spread out a little, to allow all the worms to get to the food. Besides your worms, there might be other creatures in the bin, such as pill bugs and white worms. These help breaking down the organic material, and should be left alone.



Harvesting the Worm and Compost

After a few weeks, it is possible to start collecting the vermicompost and worm castings. In the bin, you will see soil-like materials, called worm castings. You will also find decomposed bedding and food scraps, which is the vermicompost. When there is a lot of these materials, it is time to harvest. Harvesting can be done in one of two ways:

The first process is done inside the bin: Put the food on one side of the bin for several weeks. This causes the worms to migrate to that side, allowing you to remove the content on the other side. Remember to refill the bin after you take out the material. Repeat the process by placing food scraps in the new bedding area.



The other process is done outside the bin. Gently dump the contents of the bin on a plastic sheet. Leave the pile for 20-30 minutes. This causes the worms to burrow into the pile. You can now carefully harvest the top layer of vermicompost and worm castings. Repeat until only the worms remain. When doing this, you might come across light brown lemon-shaped dots about the size of a grain of rice. These are worm eggs, and should be left in the pile. When you are done harvesting, place the worms and eggs back in fresh bedding.



Using Vermicomposting and Worm Castings

To show the worms how much you appreciate their labor, use the compost and castings both indoors and out – your plants will say “thank you”. Outside, the compost and castings can be used as mulch around plants or as a conditioner for your lawn. Indoors, the harvested material can be mixed with potting soil, or you can make compost tea (steep two tablespoons of vermicompost with a quart of water for a day).




Conclusion

Any household of the STAR community can use this process of making excellent soil. Worm farms are a great way to reuse food scraps you would normally throw away.
