Cheap and Easy Worm Farm

I made a worm farm out of two plastic bins and used coffee grounds. It was so simple that I couldn’t help but share it. Of course you will need worms to get started but they will quickly reproduce so you don’t need more than 500 to start. I bought some red wiggler worms, also known as composting worms on Amazon

along with a couple of dollar store totes. Since I worked at an office I asked the night janitor at work to save the coffee grounds for me from the multiple coffee pots she was changing out every night. I have heard people say they also got coffee grounds from Starbucks or other local coffee shops. They are usually happy to give you the used ground instead of throwing them away if you just ask. You can also throw in used tea bags and ask friends and family to save their coffee grounds and paper filters.

First I drilled holes in the bottom of one plastic tote.

I then placed some old coffee cups in the bottom of the plastic tote that was not full of holes. You can use anything for spacers, I just happened to have some old coffee cups. Then I placed the plastic tote with holes on top of the coffee cups. This way, the water from the worm bin can drain into the void and not drown the worms. Also you can harvest the “worm tea” for fertilizing your plants. It works great!

I filled the top tote with coffee grounds and sawdust.

The worms will also eat the paper filters, tea bags and the sawdust.
I put the worms in the coffee grounds, placed the sawdust on top to keep flies from laying eggs in the coffee grounds and wet the whole thing down. I put cardboard on top, the worms will eat that too!

Occasionally I put leftover vegetable scraps in the coffee grounds as well. The worms multiplied quickly and I would feed them to my chickens at times over the winter to supplement their diet. Eventually I moved the bin to a larger tote and then put it in my 300 gallon Rubbermaid livestock water bin (minus the water) when I decided to make a container garden in the spring.

It was such a success that I thought I should share it with you. Once my garden is spent, I will recapture some of the worms put them in my small tote and keep them indoors for the winter. The rest of the worms will be great for my chickens and compost pile! I think I will try meal worms next. They are so expensive to buy at the feed store….stay tuned!
