How To Set Up Worm Compost Bin

Use nature'southward digesters to assist eliminate nutrient waste product and produce food-rich compost for your garden or house plants.

The lowly worm gets almost no respect and is synonymous with an insult. This apprehensive fauna toils tirelessly eating the garbage of life and bulldozes its way through the clay nearly blindly, with no eyes or ears to guide it.

But, as you might guess, worms take an of import place in every ecosystem. These legions of tiny diggers include over 5,000 species and, according to Charles Darwin, humans wouldn't exist without them: "It may exist doubted whether there are many other animals which have played then important a part in the history of the globe, as have these lowly organized creatures," he in one case wrote.

Why compost with worms?

The good news is that you can harness this incredibly efficient composting power for yourself and alter the manner your family disposes of waste, with very picayune investment of time and money. A homemade worm composter costs about $xxx and a luxurious store-bought worm hotel ordinarily won't toll more $150. If yous consider the cost of purchased organic fertilizer for your garden, even the almost expensive composter could pay for itself in one growing flavor.

Worm composting, also known as vermicomposting or vermiculture, produces natural, odor-free compost that takes about 30 minutes per calendar week to maintain. The biggest time investment is harvesting your worm castings (the precious poop/garden fertilizer), and that happens nearly every 3-6 months.

Tin can worms truly exist the panacea of stink-free composting that many people merits? Yeah, if you exercise things the right way. The proof is in how many municipalities promote vermicomposting as a way of diverting food waste material away from landfills. Worm composting is now as well used widely past large commercial dairy farms every bit one of the most efficient means of processing manure.

Setting up your worm composting bin

A worm composter is, at its simplest, a bin with holes for ventilation and moisture. It'southward almost always made with plastic and raised off the ground to allow water to drain out the bottom.

For indoor worm bins, this is done with a plastic storage bin or tote with a lid. Simply drill a series of holes in the sides and bottom a few inches apart, not including the lid. Worms don't need light, and even though there shouldn't be much moisture coming out the bottom, the holes are there in instance it needs to bleed. The side wall holes are for better air flow.

If you lot make up one's mind you lot want your worm bin outside, many people have been successful using a simple woods box with gaps between the planks (similar a pallet). This is lined with a heavy-duty plastic, such as greenhouse plastic, which is punctured with holes for drainage and airflow.

Both types of bins need to exist raised up. A plastic bin tin exist prepare inside a slightly larger 2d bin, and many people recommend a big tote that will completely envelope the kickoff bin. In fact, this blueprint often leaves out the lid on the commencement, inner bin and uses the large lid of the 2nd bin for protection. In my feel, however, I take found that this closed-up environs completely counteracts the ventilation holes and makes the bin retain besides much moisture.

Instead, the Ecology Protection Agency has recommended a not bad bin design with a short bin acting every bit a tray to catch any drippings from the larger bin. The one matter this design doesn't include is elevation, which can exist accomplished by gluing a few small plastic food containers (such as for foam cheese or sour cream) upside downwardly on the lesser.

The pallet bin should simply accept 1 pallet on the bottom as the floor. With any worm bin design, the goal is good ventilation, darkness, and drainage.

What type of bedding is all-time?

The next step is bedding for your worms. You can use:

leaves
straw
shredded paper
shredded cardboard
egg cartons

I recommend leaving out the leaves and harbinger if it'due south an indoor bin, because these materials can introduce insects and other outdoor creatures that you might not want reproducing inside your house.

One time you've prepared a overnice bed, add a big scoop of garden soil. You can use a big juice bullpen filled with clay, and so use the aforementioned bullpen to pour in some water. You desire the moisture level to be the same as a wet sponge – not besides wet, not as well dry out.

If y'all make the bedding as well wet past accident, add more than dry out material and/or permit information technology drip off. Don't get anxious and add together the worms before the bedding is right. I made that mistake one time, and it was very difficult to bring the wet level downwards later because calculation nutrient waste product raises the wet level dramatically in the bin.

Where should you put your worm bin?

We've talked virtually both inside and outside worm bins to a higher place, but they both have their pros and cons in whatever climate. When your bin is exterior, there are 2 big benefits: capacity and a lot less attending to item. You can put your worms out there and not accept to worry so much about getting it just right, because it won't thing if it smells a niggling more. But if y'all live anywhere other than very warm climates, your worms will either die in the winter or y'all'll have to bring them inside anyway.

With an inside bin you can keep worms even in an apartment, only your capacity will always be limited – you volition only exist able to take a certain amount of worms, which will eat only a certain amount of food, or it volition go stinky and become wrong.

Buying your worms: getting what you pay for

The type of worm nigh commonly used for vermicomposting is the red wiggler. That's why this method of vermicomposting is also chosen red worm composting. The red wiggler species (Eisenia fetida) loves living in rotting organic material and manure and is extremely efficient at breaking it down. Dissimilar your typical garden earthworm, they don't mind living in a small bin and won't effort to burrow down deeper.

Blood-red wigglers used to but be bachelor at bait shops for fishing, but today they accept get and then popular, there are many companies that will transport them to you past the bag. A pound of worms will eat their half their torso weight in waste material every day, so if you collect your food waste material and weigh it, you lot tin can come across exactly how many worms you'll need.

A pound of worms includes virtually k worms and should exist more than than two large handfuls. Here'due south a video of what 1 pound of worms should await similar.

It'southward important to know how many worms you should be getting, considering your worm bin could neglect without this information. Twice my own worm bins had a fly infestation that compromised the bin. I couldn't figure out why. It turned out that two different companies severely shorted me on the quantity of worms, because I had no idea what a pound of worms should look like. The result was that I put in far likewise much nutrient for the worms, and the waste rotted and bred flies.

What should you feed your worms?

Worms can swallow almost whatsoever fruit or vegetable food waste. Don't give them anything that comes from an animal—no fats, basic, dairy, or meat. They also have a difficult fourth dimension with some stems and the outer layers of onions, and they can't handle also much citrus. If you have a bunch of orange peels or other citrus, make sure it doesn't make up more than than i/five of the total waste matter you lot are adding. Never give them dog or cat carrion, or any carnivore feces. Merely you lot can add coffee grounds, filters, napkins, shredded paper towels, and non-plastic teabags.

To add food to your bin, dig a hole and bury it beneath the pinnacle layer of bedding. It helps if you break up the larger pieces. You lot should also add together a scattering of shredded paper and bank check if in that location's something left over that the worms are avoiding from previous feeds. Remove annihilation they won't consume.

Equally mentioned before, worms volition eat half their body weight every twenty-four hours. However, when you showtime become them they will be a little slow to commencement. Begin with modest amounts of food and check to encounter how long it takes them to consume it. Increase the amount until you are calculation the equivalent to half their weight daily.

If they seem to be leaving a lot of waste material, chop up the food y'all're adding into smaller pieces. You can realistically look one pound of worms to eat at least iii pounds a week and twelve pounds of waste per calendar month.

Troubleshooting worm composting bug

Being a stickler almost how much food you add together to your bin will help prevent a lot of problems. Hither's how to deal with common worm bin issues:

Your worm bin has fruit flies: If you lot've already saved compost on your kitchen counter, y'all know how piece of cake it is to go a fruit fly infestation. Prevention is central. Make sure to encompass the food waste well under the bedding, cut information technology up into piffling pieces, and don't allow annihilation sit and rot in the bin.
Your composter stinks: If your compost starts to odor, dig through the bedding and remove any food waste product that appears to be rotting. The worms should really exist eating anything earlier it can get moldy, but they may let something sit down to soften upwards. For case, they probably won't eat a whole fresh banana pare until it starts to pause down and softens up. Cutting upwardly larger pieces will aid them process food faster. A bad smell tin also signal a wet problem. Too much rotting waste matter tin create a lot of humidity, which will soak the bin and make it a little likewise damp for the worms. Add some dry out paper-thin and newspaper bedding to assist balance things out and get the bedding dorsum to a spongy moisture level.
Worms are crawling out of the bin: Information technology's normal for a few worms to come out of the bin, but if yous accept a lot of escapees, you probably have an environmental problem. This volition include wet, temperature, and possibly even infestations. If the bin is too dry, add some water. If it's too moisture, add more bedding. Check for insect larvae or other issues under the top layer of bedding.
At that place'due south an infestation: Sometimes other creates will love the moist, dark surround of the bin— even just to lay their eggs. If you lot notice insects, eggs, or even furry creatures, have the bin outside and harvest the castings. This is a good time to clean out the bin and remove any rotting nutrient or erstwhile bedding. First off fresh and put the worms dorsum in their dwelling. If you lot had a rodent invader, hold the lid down with bungee cords or rocks.

Helping your worm compost thrive: amendments

If troubleshooting fails to correct your trouble, consider adjusting your worm bedding with one of the following amendments:

Material	Purpose
Coconut coir	Balances out nitrogen-rich materials like kitchen scraps and grass clippings, controls wet, and improves quality of worm castings.
Glacial rock grit	Enhances the microbial population, increases nutrients, and improves water retention.
Pumice	Increases air circulation, prevents matting, and controls moisture.

Harvesting your finished compost: lure vs. dump methods

At that place are ii main means to harvest your worm compost: by dumping it out completely or by luring the worms abroad from the completed compost. In my experience, the dump method is easiest if you have a small homemade bin. The lure method works well if you invest in a stackable system like the Worm Factory 360 Composter.

Lure Method
Composters like the Worm Factory 360 permit y'all to harvest compost from your bin easily, without dumping out the worms. They also remove some of the risk of stink by having a better drainage system than a bin with holes in the bottom.

Equally the bins fill up with compost, you add some other stackable tray on peak. The worms migrate upstairs to the new layer of organic waste, lured by the presence of fresh food. The finished compost is left behind in the lower trays: it's that simple.

The Worm Manufactory 360 likewise offers a refill kit that includes coconut coir, gravel rock dust and other materials that volition help keep pH levels in balance and promote stink-free, aerobic composting.

Dump Method
To harvest compost from your homemade bin, the easiest method is to dump the contents upside down on a tarp in the sunshine or under a brilliant light. The worms volition travel down to the bottom of the pile, which was your top layer of bedding (and the not-composted material). You are then free to scoop off the compost from the top of the pile and from around the worms.

This is a practiced time to clean out any unwanted $.25 and add new, fresh bedding.

Where can I use worm compost?

Worm compost can be used similar whatsoever loftier-nutrient fertilizer: sprinkle on the surface of the soil or mix in around plants, but be careful not to add together too much considering it can burn tender stems.

The liquid that drains from the lesser of the bin is a highly concentrated worm compost tea (or worm leachate). This tea should exist diluted at a ratio of 1 part leachate to ten parts water to prevent any burning.

Caring for your worms

If weather condition are right in your composter, your red worms will breed when they are over 2 months old. That means your first batch should double their population within a few months. Don't worry most overpopulation, however. If there's not plenty food, some will die and compost into the soil, keeping the bin in residue.

Worms tin live 4 or five years, but they probably won't final that long inside your bin. That's why reproduction is an essential part of keeping your bin going. You may outset to run into baby worms right away. A Worm Factory 360 tin hold over 10,000 worms, so it will probably take a while for you to get to the indicate that you'll need a second bin. This is another huge benefit of the Worm Mill: it can hold 10x as many worms in an 18" space.
