Hi friends. I've got another great guest post for you today. Adrienne, who lives in Bellingham, Washington and blogs at Crafty Little Gnome, is sharing tips for success with Vermicomposting. That's composting with worms, for the uninitiated, but I'll let Adrienne explain all of that to you. Check out the post and be sure to visit her blog, as well. There are many, many ideas that will undoubtedly appeal to small measure readers.Vermicomposting

Vermicomposting is a fancy name for composting with worms. When red wrigglers are added to your compost pile, they eat your organic waste and convert it (via pooping!) into beautiful rich compost. Worms will breakdown your compost pile much faster than traditional compost methods. Whether you live on a sprawling farm or atop a city skyscraper anyone can learn how to vermicompost. The set up is easy, takes up little space and will produce compost year round.
The Set Up
There are two routes you can take, you can buy or DIY.
Buy
Worm bins such as the Worm Factory and the Worm Factory 360 are available to purchase. They are upward migration composting worm systems. Meaning, they have layered trays and the worms travel upwards through holes in the trays to eat fresh food. You rotate the trays as the food breaks down into compost. There is also a spigot at the bottom for collecting worm tea (more on marvelous worm tea later.)
DIY
Don’t like the hefty price tag that comes with pre-made worm bins? Make your own! Making a bin is actually quite simple and inexpensive. You can use Rubbermaid bins with holes drilled into the bottom to create a worm bin. I could get into the specifics but I would probably need to dedicate a whole post for the tutorial. Google, “how to make a worm composting bin” for about a million different DIY options.
Place your bin in a cool, dry easily accessible place where the temperature is between 40-80 degrees. The kitchen is usually a great place for your worm bin. If set up properly your bin won’t smell or leak. You’ll be amazed at how fast vermiposting becomes part of your daily routine.
Prepping the Bin
Once you have assembled the worm bin begin by adding your base material. Fill it with a mix of shredded materials like old newspaper and cardboard, leaves and peat moss . Then add in some food scraps and let it sit for about a week to start decomposing before adding your worms.
Where to Get Worms
Worms are likely available at your local garden center. You can also order them online. I actually got mine off Amazon (yes you really can buy everything off Amazon) Now before you go digging up some squirming worms from you backyard remember not all worms are created equal. Some species won’t want to eat your garbage. Also, they may carry disease. For the best quality worms it’s best to buy them from a source that specifically sells worms for vermicomposting. If you know someone with an established worm bin you could always ask if you can have some of their worms. In general you need about 1-2 pounds of worms to start with. When adding your worms for the first time keep the lights on in the room your bin is situated in. Worms don’t like light and will burrow themselves into the compost to hide from the light.
The worm population of your bin will self regulate. What this means is that they will only reproduce as long as there is enough space and food to accommodate themselves. Your worms won’t reproduce to the point where the number is out of control but they do multiply quickly. You’ll notice a lot of little baby worms in your compost from time to time. This is a good thing.
What Worms Like
*Food cut up into tiny pieces (easier for them to chew)
*Veggies and veggie scraps. Didn’t get around to eating that spinach and now it’s wilted and gross? Toss it in the bin.
*Starches: Potatoes, pasta, rice, crackers and stale bread. Mmm.. Carbs…
*Dead flowers
*Disease free plant trimmings
*Coffee filters
*And pretty much anything you would normally put in your regular compost
What Worms Dislike
*Coffee grounds. Yep, contrary to popular belief worms don’t like coffee nearly as much as we humans do. In fact if you have been adding grounds to your worm bin all the brown stuff you think is amazing worm castings are probably undigested coffee. A little coffee is okay but I prefer to keep it out of the worm bin and save it for my worm free compost and other gardening projects.
*Too much citrus. Try not to overload the bin with orange peels and lemon rinds. The worms don’t like the acidity.
*Inorganic matter. Don’t forget to peel the stickers off your fruit. Worms wont eat them and you’ll find random bits of plastic in your compost. Ditto with saran wrap and aluminum foil
*Dairy and meat.
*Too many garlic or onion scraps
The food mixture should be about 50% kitchen scraps and 50% fiber.
Sources of fiber:
*Shredded paper
*Magazines
*Cardboard
*Dryer lint
*Kleenex
*Napkins
1lb of worms will need about ½ pound of food per day. Your worm bin should never smell bad. If it stinks there is something wrong. We’ll get to the troubleshooting section shortly. Now, about that amazing worm tea I mentioned…
Worm Tea
As your worms get to work churning out the compost you’ll notice a collection of brown water in the bottom of you bin. This my friends is known as “worm tea” Worm tea has all the nutrients and benefits of compost but in liquid form. Your flowers and plants would love a cup or two of worm tea! You can use your worm tea as fertilizer for you plants. Water your house plants or garden with worm tea and watch them grow to new heights. This stuff seriously rocks.
How to Harvest
So a few months have passed since you welcomed your new worm friends into your home. You provided them with a safe, dark, temperature controlled home with plenty of food. They kept up their end of the bargain by eating your organic waste and providing you with dark rich compost. A collection of compost has built up but what do you do with it? Once you start gardening with compost you will find you can never have enough. You can add your compost to new or established garden beds or to potted plants. Anything growing in dirt can benefit from added compost. Before you harvest your compost bury a piece of food in one corner of the bin and the worms will migrate towards it. The next day carefully collect the compost and try to pick out worms and place them back in the bin.
Troubleshooting:
Help! There are flies and bugs in my bin!
A few flies and bugs are normal. The worm bin is a complex eco system full of different bugs gobbling your decomposing food. If there are suddenly too many and they are a nuisance stop adding new scraps and bury the current decomposing scraps deeper.
Oh no! Some seeds have sprouted and there are little plants growing in the bin!
Not to worry. Little plants never hurt anyone. It’s quite common for seeds from veggies such as squash to sprout and grow in the bin. You can prevent this by zapping your seeds in the microwave for a minute before placing them in the bin.
Yikes, there is moldy fuzz growing on some of the food!
Help prevent mold by turning the compost every few days. If there is too much mold it may be a sign you are adding too much food to your bin too fast.
My bin is too dry. How do I add moisture?
Soak some newspaper in water and ring it out. Place it over the top of the compost. Your compost should be fairly moist but not dripping. The composting matter should have the moisture level equivalent to a damp sponge.
My Bin is too wet. How do I control the moisture?
Add some shredded paper. Worms need to be kept moist at all times but if it is too wet they may drown.
Sniff sniff what’s that smell?
If your compost is getting stinky stop adding new material and turn your compost. Try to bury uncomposted materials.
Once you get your bin set up the maintenance is quite easy. It’s amazing the amount of items you are able to compost and how quickly it will break down. Whether you purchase a premade worm bin or make one yourself you’ll find worm bins are not only a great way to create your own compost but also a fun project for the home and a unique way to get kids interested in gardening and science. Are you ready to have worms start eating your garbage?

I have a homemade vermicompost bin that I keep in my basement. It cost me $8 to make and consists of two storage containers stacked inside each other. I drilled 1/4" air holes in the top, bottom and sides of the inside bin. The outside bin catches the worm juice that drips out of the bottom holes and I pour it off when it starts to accumulate. This was my second attempt at building a vermicompost bin, because I just couldn't justify spending $80 plus on a commercial stackable unit.
ReplyDeleteFor my first attempt, I used two buckets which wasn't large enough so everything just rotted on top with the worms staying at the bottom. My current bins are large enough that I can put the new kitchen scraps on one side, and then scoop the worms from side to side, wherever the fresh scraps are added. The worms curl up in the egg shells because they love the calcium and can break down food waste incredibly quickly. I would not advise adding paper with colored ink on to your worm bin, if you are using the castings on plants you will eat. Colored ink, that's on most newspaper and junk mail, has heavy metals in it and you don't want to add that to your veggies. I sort my paper so that the worms get used tissues and other types of pulp, including a few shredded Fall leaves.
My outdoor plants are thriving on the worm juice and I use the worm castings when I make compost tea. Usually in the Spring, when the worms have reproduced to more than the bin can sustain, I add them to my outdoor chicken manure compost bin and they get to work in there.
I highly recommend vermicomposting, especially in winter when you have to battle snowdrifts to get to the outside bins, it's nice to have another bin close by.
Wow, this is great information and such a thorough explanation of how to set up this kind of bin. Just what I've been looking for as this project has been on my list for a while but seemed a little daunting. Thank you so much for the step-by-step instructions and encouragement!
ReplyDeleteGreat post! I have a question, can I add pine shavings and chicken poop from my chicken coop or will that harm the works. I already have a vermicompost bin and I want to start composting my chicken droppings can I add them in my vermicompost bin?
ReplyDeleteAnd thanks for the tip on the coffee grounds. I had heard from others that it actually sped up the worms metabolism. I'll stop adding them to my vermicompost bin.
