We can all agree that bedding is one of the most important upkeep elements in a worm farm. Adding at least some bedding on a regular basis is essential to keep your red worms happy and productive. Failure to do so can result in all kinds of problems, even death to your worms!
It can’t be emphasized enough, then, how important it is to provide adequate bedding to your worms. But what kind of bedding can be used in worm farms? Well, we here at Uncle Jim’s Worm Farm know of many bedding materials that work really well!
You need to choose wisely, so let’s dive into some common types of bedding and explain how you can make the best worm bin bedding.
What Is Worm Bedding and Why Do You Need It?
Worm bedding, a.k.a. worm bin bedding or vermicomposting bedding, is used to create a comfortable and healthy environment for worms. It provides worms with optimal conditions to live, eat, and reproduce.
But what’s the point of worm bin bedding? Well, the purpose is to provide your worms with a source of food and a comfortable living environment. The worms feed on the bedding and break it down into nutrient-rich castings, which you can later use as a soil amendment or fertilizer. The bedding also provides a space for the worms to move around and burrow, which is crucial for their overall health. So, it’s definitely a significant part of worm composting.
The Must-Have Worm Bedding Characteristics
From the moment you set up your worm farm, the most important thing to do is make sure you use the right kind of bedding material. The best worm bedding materials must have these characteristics:
- pH neutral
- chemical-free and non-toxic
- allows oxygen flow
- retains moisture
- free from abrasive things that can harm the worms’ sensitive skin
So, the ideal worm bedding should be moist, well-aerated, and have a neutral pH level. Also, it should be able to retain moisture without becoming too wet or compacted.
Good bedding can also be eaten by the worms. In fact, up to 50% of a worm’s diet may consist of its bedding. One material that works extremely well for both bedding and worm food is brown cardboard because red worms love eating brown cardboard. You should shred it into small pieces to allow for better airflow so the worms can eat it more easily.
10 Common Bedding Materials Your Worms Will Love
The key to maintaining a healthy worm bin isn’t choosing just one “best” bedding material. It’s using a variety of materials and adding them to your worm bin often. Most vermicomposters could do a little better at adding new bedding to their worm bins more frequently.
Here are some options that make for the best bedding for worms:
- Shredded brown cardboard
- Shredded paper (not bleached white office paper)
- Shredded newspaper (not colored)
- Aged compost
- Aged horse manure or aged cow manure
- Coco coir
- Peat moss
- Straw and hay
- Fall leaves and other yard waste
- Wood chips
The key is using a combination of bedding materials to allow your system to operate most efficiently and be well-balanced. This is because some materials are inherently better than others, and adding several types into your worm bin will make up for certain weaknesses in some of the materials you may have on hand.
When creating a bedding mix, try to balance carbon-rich materials (paper, cardboard, or dry leaves) and nitrogen sources (such as food scraps or grass clippings). A good ratio is roughly three parts carbon to one part nitrogen.
When the bedding has reached desirable conditions, the worms will thrive, and production will soar. Be attentive to this, and your composting worms will be happy.
How to Prepare the Bedding
Once you have the right choice of bedding, it’s time to prepare your red worm bedding. How do you do that? It’s simple – here’s what to do.
- If you’re using paper or cardboard, shred it into small pieces.
- Dampen the materials before adding them to the worm bin. They shouldn’t be sopping wet, just damp.
- Squeeze out any excess water.
- Add the bedding to your worm bin.
Don’t forget to fluff up the bedding, every now and that. That will keep it from compacting and stinking. This also creates air pockets where worms can move around in. Also, remember to feed the worms in different parts of the bin.
Maintaining the Ideal Bedding
Of course, you can’t just mix all the materials, add them to the worm bin and forget about it. You need to keep a close watch and maintain the bedding properly in order to keep your worms alive and healthy.
As your worms begin to eat the bedding, it will start to break down and become compacted. To maintain the bedding, you’ll have to add fresh bedding from time to time to keep the environment healthy.
Remember to regularly monitor the moisture level and adjust as necessary. But be careful – if the bedding becomes too wet, it can become anaerobic and produce unpleasant odors. On the other hand, if it is too dry, the worms may not have enough moisture to survive. So, what you need to do is add water or dry bedding material as needed to maintain the proper moisture level.
Make Worm Bedding Today and Help Your Worms Thrive
How can you make sure your worms are happy and productive? By giving them the right kind of bedding on a frequent basis! And as you can tell, finding the best worm bedding and adding it to your worm bin isn’t a hard task.
You just need to choose wisely and use the right materials that serve as excellent bedding and a food source for worms. From there, it’s all about keeping a close look at the bin and making sure the worms are happy and healthy in their living environment. Good luck, and happy vermicomposting!

do you sell coco coir?
Hi Ginger! We do not sell the coir, I apologize. Here is a link to a great company that does > http://natures-footprint.myshopify.com/products/worm-factory-refill-kit?variant=14215648451
Have a great day!
No I am sorry we do not.
Do they like leaves or cardboard better?
They like leaves better
Hi, your suggestion of the manure is really conflicting me. Many cattle farmers (all?) Actually “worm” their/our animals to kill the parasites that naturally accumulate in their gut and cause them to grow more slowly. This is a pesticide which persists in the manure and even after aging I wouldnt be putting it anywhere near my wormies. The lack of information in your article about this important and potentially deadly pesticide use could be very misleading to those unaware of its presence.
Our first worm farm we started, we gathered manure from neighbors and were told they had not been dewormed. We lost over a thousand dollars worth of worms, bedding, supplies do to dewormed manure. We could not use anything associated with or that might have come in contact with the taunted manure. Be sure of what you feed your worms.
how do you get the gold from the worms? right now I go through the dirt with my hands and put the worms inn another container. is there an easier way?
make a pile, shine a light on it, the worms will avoid the light and head to the bottom of the pile, you can then scoop from the top of the pile where the worms have left. repeat! hope this helps
Yes a flow through worm bin
You can build a side by side bin too. One big bin sperated by a hardware divider. Grow your worms on one side, then when the dirt is ready, start feeding the other side. The worms will move to the other side and after a few weeks you can harvest the dirt. You may still have some baby worms and cacoons over there, though, friending on how long you wait to harvest.
We have pine shavings, as well as cedar ~ kept around for our bunny. Would either of those work well – or should either or both be avoided?
You can use pine and cedar shavings as bedding, although we would not recommend using only that as bedding. Wood chips can provide bulk and create air spaces throughout the bedding, when mixed with other beddings. They can also be reused, as the worms will not compost them. Keep in mind though, wood chips or shavings can dry out easily, so you would want to mix them with something that retains moisture.

What do you think of Sphagnum Peat Moss? And, if you like it, how much would you recommend for a bin?
Hello Sherryl! Yes, this is what we use and recommend as a source of bedding. We recommend having it kept about as moist as a wrung out sponge and between 40 and 80 degrees for the worms. The pH should be kept neutral. Hope this helps!
If ph starts to shift how do you adjus it?
Would grass clippings be ok.
Yes I have used them and plan on using them again.
Would grass clippings be ok.
Hello! Yes, grass clippings are fine to add to your bin. I would recommend letting them age a little while so they are not so hard when you add them. Have a great day!
Just got 500 worms via Amazon from you guys yesterday! Added them into my bin and I think they’re happy. My current bedding is a mix of coco coir, shredded fall leaves, and shredded paper egg cartons. I want to add some more bedding on top and it was going to be shredded newspaper. But, I can’t find any black and white newspaper here in town.
Can I use shredded brown “Kraft Paper” in my bin? I have a big roll of it I can shred up for the little guys.
Hi Nick! Yes, you could add this paper as another source of bedding. Make sure that it is shredded and kept about as moist as wrung out sponge. Have a good day!
Is shredded brown cardboard boxes and bags from fast food places that have colored ink safe for worms, or should these areas be cut out before shredding? W the gray paper beverage trays (cup holders) alright for bedding?
Using shredded cardboard boxes/broken down cardboard cupholders/paper bags should be fine for the worm bin. As for using newspaper/paper with coloured ink, we do not advise it since it is coloured. However, many inks today are toxic-free.
I saw a post today on a youtube news site saying that the wrapping and packaging for fast food, esp M contains toxic chemicals. carcinogenic to humans. don’t know about the wigglers, but they seem somewhat sensitive to unnatural stuff.
can i use worms from local bait shop? and what about mixing red,night crawler etc??
Worms from local bait shops are generally nightcrawlers of some sort, which are fine to mix with the worms you have. Mixing both European nightcrawlers and red wigglers does not hurt either of the worms since they live in basically the same environment.
Can I use p-nut hulls as a source of bedding
Yes. P-Nut hulls are just fine as a source of bedding and food for compost worms.
Can I use chicken manure in the worm bedding? Does it need to be aged first?
You can use it. But don’t use much and yes make sure its aged if possible as it has a lot of ammonia which will hurt the worms.
You wrote – “Also, remember to feed the worms in different places.” – What does this mean?
Ray – I assume different places around your bin. i.e. I put scraps in SW corner, then next time in the NW corner, next time NE corner…
How much shredded newspaper is ideal for the bedding?
I see that rock dust and pumice is included with the kit from Worm Factory 360. But no where does it say how to use it. Wouldn’t that be rough on their little bodies? or cut them?
Thanks for all your help
Does sawdust work for it?
Does sawdust work for bedding?
You say to fluff the bedding periodically. I have also read to not disturb lower trays. Does one only fluff the top tray or should lower trays be fluffed?
why not bleached white office paper? multiple other sources say it’s OK to use as bedding in moderation. just wondering if it’s bad because it’s bleached or if its because too much can lead to excess carbon.
Every time I have used any kind of paper mine have died.. I think they need a good bit of dirt to eat also
How do you check the PH balance of the worm bin?
I just wanted to add that ants are terribly mean to worms,. I’ve seen a few people ask if they will hurt worms and YES THEY WILL ATTACK THEM.. its horrible..
Also do u have food I can buy? I’m having trouble coming up with stuff to feed them.. I don’t have very many but I don’t want to be just put grass in there.. Ive been putting banana peels cut up but that’s all
Can I put boughten potting soil in there?
Hey there, very informative, thanks. I was wondering can I use fresh water clam shells if I boil them and grind them to powder in a coffee grinder? Will this make a reasonable grit for their digestion in place of egg shells? thanks.
I would not suggest the use of newspaper as garden mulch .
I am a touch confused. Is bedding different than what you feed your worms? I have access to a lot of manure/hay/straw mixture ,grass clippings and leaves. My bed is going to be 24′ x 4′ decided in the middle. Aging manure on one side and working tie other. Do.i need to collect some news paper and cardboard. Or just use the stuff I mentioned above.
Bedding is the material the worms live in and breed in. You feed them your household vegetable scraps. The worm castings they create make a wonderful soil amendment for pot plants and vegetable beds. If I had a supply of manure, straw, and grass clippings I would mound it up and make a ragular compost pile without the worms.
I’m wondering about using the bedding — can the shredded newspaper just be mixed into the soil & kitchen scraps or does it need to be a separate layer underneath? I’m also confused as to how to keep it “airy” if it’s wet, it kinda flattens down.
Sorry for the (silly) questions, but I didn’t actually intend on having a worm bin inside, but I found some little earthworms in a pot of lily bulbs that I’d brought in for the winter — and I couldn’t bear to just chuck them outside in -30F weather, because that would have killed them, so I set up a worm bin using the soil that the lily bulbs were in, some shredded newspaper & some kitchen scraps (fruit & veggie trimmings).
There were 6 worms in total — which was a shock to me, because the soil was completely bone dry, then the bulbs started to grow so I threw some water on them …. then went to separate the bulbs to pot individually, and found baby slugs (UGH) and these earthworms. Two were red wrigglers, and the other 4 are these little dudes that I usually find in my outdoor compost bins or under grass clipping mulch (they seem to really like grass clippings!). They’re about an inch long, they hardly wiggle around at all & one end is bright orange. They are usually just hanging around, fairly straight, with a slight c shape.
Thank you for reading this, and thank you in advance for any guidance as to bedding and what kind of worms these little ones might be 🙂
I have a couple of plastic indoor bins located in the laundry room. I have had the worms (eisenia fetida from Uncle Jim’s purchased through Amazon) since March of last year. My bedding consists of: shredded cardboard,egg cartons,brown leaves, a small amount of white paper, and shopping bags; some peat moss with a little bit of lime for ph buffer; and, rabbit droppings with hay/straw mixed in. I wet all these stuff together until I have a bedding with a moisture content of a wrung out sponge. My bins don’t have holes or rocks in the bottom. It is solid bedding. I don’t have a cover for the top except for dry shredded cardboard and/or egg cartons. I have never had an occasion where the bedding dries out. I even put dry materials under the food scraps I put in to prevent too much moisture.
I feed my worms vegetable and fruit scraps that I either run through the blender or have aged in a covered container mixed with coffee grounds. I spray a small amount of diluted molasses on this. I also feed them a small amount of homemade worm chow and ground up egg shells.
I feed them until the bedding has shrunk to about half the volume or thereabouts. At this point, I stop feeding until I am satisfied with the look and feel of the compost in the whole bin which resembles coffee grounds. I resume feeding and after a few days, I lift the whole mass of worms covering the food and transfer it to a new bin. I do this until I have harvested most of the worms. I put just a tad bit of food in my finished compost for some worms that might be straggling or haven’t hatched yet. I sift with a fine mesh what I need for my gardening needs for as long as I still find worms. I keep my finished compost moist by covering the top with a damp sheet of newspaper and a lid with holes on it.
Beneficial information gathered from various sites enabled me to have a worm composting set up that is easy to maintain and makes use of available materials.
This from a Filipina who has an aversion (phobia, really) to earthworms growing up! Thank God for gloves! Hope you have a wormie day!
I’m also a Filipino who likes worm composting. Your post really helped. Thank you.
How long does chicken poop need to be aged? I was looking into possibly worm composting wood shavings and chicken poop from 3 chickens…Maybe I should just stick to regular old non-worm compost?
If some red wigglers get in the garden is it harmful to the earth worms
I have just started with worms brown cardboard are you talking about cardboard boxes I thought boxes would have glue on it would that harm the worms ,thank you Therel
will red worms eat the mealworm bedding? And will it be ok for the red worms?
Can I use top soil mixes with peat moss for worm bedding and how long my I keep
the bedding without having to replace it, also can I add newspaper and cardboard every now and then?

What’s an acceptable TDS meter reading for worm bedding? I’m considering some coconut coir that reads at 300 on a TDS meter, is that too salty? Thanks!
Can I use scrapbooking paper in my worm bin? It is acid free but is colored paper.
What can you feed for the earthworms??
Does peat moss will kill my worms ?
I bought a lb of worms last year and put the in my composting Bin which was half full. No bedding added. Those guys multiplied significantly. When I harvested the two and half months later, I had about 14 lbs of worms. This year I will be experimenting with the recommended way of feeding my other bin( 1″ of food on top of bedding to see which is more effective.) I should point out that it’s a pallet outside bin.
Hello, to those who are composting and using vermicultura to improve our growing media in an environmentally friendly way:
DO NOT EVEN THINK OF USING SPHAGNUM MOSS in either a compost mix or as bedding for worms.
The extraction of peat moss is seriously damaging and only recoverable over millennia.
Just do not use it !
Hello, Is orchid moss okay to use as bedding for my worms?
Can I make my bedding completely from cedar and pine shavings?
Is pine bedding bad or good. I bought pine bedding like for rabbits, hamsters and such, to even brown and green in my compost with my worms. Will it hurt my worms. I sure want to know.
Will Miracle gro peat moss hurt my worms?
I have a question, I am raising nightcrawlers for fishing. My first attempt the majority died over night. I put some cardboard squares about an inch square on bottom, maybe an inch. I then put peat moss mixed up with water from water hose about 12 inches deep. I have drain holes in bottom, plenty of air, soil temp. was 62. The worms that were alive were in the bottom in the cardboard. What could be wrong? Also when putting cardboard and peat moss, Do I mix it all together or layers? Thank you
I have a bunch of rotted wood (looks like most if not all of the work so far was done by fungi) and was wondering if it could be used as the main (85% or more) ingredient in bedding. It pulls apart easily, retains moisture well, and seems to stay airy and light. Will they eat it since its so broken down, or do red wrigglers avoid eating wood at all stages of decomp? I have a functioning bin, so this is kinda an extra experiment bin, but I’ve added a small amount of food scraps and some coco coir and the worms seem to be doing okay, but if the wood will never get broken down to castings I’m not sure I want to use it there.
is it ok to use some cedar mulch to deter insects in my bin
I have a fallen decomposing cedar tree in my yard. It breaks to very fine pieces when I apply pressure. I was thinking of adding this to my bedding. Any thoughts?
This is my first time having worms and I cut up a bunch of paper into small pieces but they have sharp corners. Will this hurt my wriggly babies? How do I soften them so they don’t paper cut my squiggles?? I’ve since shredded but don’t want to waste what I cut up already
Can brown paper bags be used for bedding
Brown paper bags will work great as bedding! You always just want to avoid any type of toxic paper product.
Yes! Brown paper bags are great to use as bedding!
Have a great day,

I have bought a second hand worm farm. I have existing compost bins which have lots of worms in them, can I use these in my wormery?
Of course! Whenever you are ready you can harvest out worms in your current composting bin and put them into your new one. The worms will then continuing to double in population every 90 days until they fill the capacity of your bin!
1. Has anyone tried using cardboard from those cardboard cat scratchers?
2. How fragile are wormlets? I’ve found a ton, ok a lot of wormlets while pulling weeds. But I don’t want to get them out of their little clump, if I shouldn’t move them. I
I started my vermicomposting(which has become 4 bins now)b with only works I found in the gardens or yard. But, at the time, I didn’t know what b a wormlet really looked like. Any help would be greatly appreciated.
I have raised worms for a long time but have recently moved. My new home has a lot of evergreens that have needle leaves. Since the coconut coir cost a considerable amount I was thinking of subsidizing some of that with the leaves. Have red wrigglers ever had a problem with this type of mulch?
hi so i am starting a worm farm and i need a little help what do you think is the best thing to do
.. “best thing to do” if you “need a little help when starting a worm farm” is to *do your research*!. Best way to do that … google! Try googling terms like “how to start a worm farm” or “how to vermicompost” … there is a wealth of information already out there on the web which is instantly accessible, without having to wait for someone to reply. Best of luck, Hannah!
PS: same goes for most of the other people posting questions … try asking Uncle Google for some answers … he’s just sitting there waiting for your questions while Uncle Jim is probably very busy with his worms!!! (just guessing)
I have some perlite that got crushed and is basically a powder now. I was wondering if I could add it to my bin to act as grit?
I’m wandering if my worm bedding is made properly? 1 year old compost with dried leaves and shredded cardboard. Compost 6 to 8 inches deep. Do I just moisten leaves and shredded cardboard and then spread on top of compost? Leaves are also mulched.
That sounds great, however, makes sure that you dampen all of the bedding through so that if you squeezed a handful of it, you would get 2-3 drops of water and keep it moist. Otherwise, that will do just fine.
Uncle Jim’s Worm Farm
Hi uncle Jim.
Before raising my questions, I’d like to expose first, some of their background.
As a new vermicompost worm grower, I searched the net in order to learn the subject from more experienced growers then myself. Threwout my inquiry, I found out that good results of the worms’ product, depend very much on bedding’s ingredients veriety, amongst which they pointed at coconut coir, peat moss, dry leaves,fine shredded paper, shredded cardboard, used ground coffee, aged compost, aged vegetarian animels manure,crushed eggshells, oister shells pouder, biochar, basalt rock dust, broken mushrooms etc.
And now for the question: What should be the best proportion amongst the mentioned ingredients, in order to get the optimal product’s result?
Another question that bothrers my mind is: How can it be recognized, that the bedding material has been completely consumed, and time has come to stop putting “fresh” food into it, and instead, put it to the alternative bedding, to attract the worms to move over there, in order to enable collecting the done product without harming the worms?
I wish to thank for answers to my questions
