The place for worm discussion of all sorts. Whether you're raising worms for composting, bait, or God knows why else, this is the place for discussion. Common topics covered are setting up new worm bins, getting high-quality vermicompost, making vermicompost tea, or common problems encountered when raising worms.


The Vermiculture Reddit

Vermicompost is the product or process of composting using various worms, usually red wigglers, white worms, and other earthworms to create a heterogeneous mixture of decomposing vegetable or food waste, bedding materials, and vermicast. Vermicast, also called worm castings, worm humus or worm manure, is the end-product of the breakdown of organic matter by an earthworm. These castings have been shown to contain reduced levels of contaminants and a higher saturation of nutrients than do organic materials before vermicomposting.

Containing water-soluble nutrients, vermicompost is an excellent, nutrient-rich organic fertilizer and soil conditioner. This process of producing vermicompost is called vermicomposting.

Does labeling my worm castings as biofertilizer subject it to regulation?

I’m starting to sell some of my worm castings to some friends and family members. Nothing crazy because I have a small operation.

I have been researching and found that calling your worm castings a fertilizer makes it subject to increased regulations. You even have to get it registered/licensed in states. But does the same apply to labeling it biofertilizer? I know a lot of people label it as a soil amendment but I feel like the term doesn’t really fully convey what worm castings can do.

If you label it a fertilizer it needs to have an NPK value. Worm castings have a low NPK anyway, so that might not be the best idea.

I’m researching it but I’m finding conflicting information about whether it needs to be licensed if I call it biofertilizer. Does any have any experience with this?

Malted Barley

The most mycelium I’ve ever seen thanks to the malted barley I’ve added. Did I over do it? What can I expect to be my harvest window?

How to care for single worm?

Hi y'all! I'm into bonsai and not worms or composting and after I bought some bagged bonsai soil for my trees I found a red earthworm in my soil! The soil for my bonsai is rocky and with very little actual soil, but I want to keep this worm alive since it's still moving, how do I care for it? Can I put it in my other indoor potted plants?

Total noob, I think I’m doing this wrong

I purchased an indoor stacked tray worm composter + 1,000 red wrigglers from Uncle Jim's worm farm in late November.

Worms seem fine. Been feeding them the commercial food from Uncle Jim's (will start adding table scraps soon, have some frozen and ready).

But after browsing this Reddit, I suspect our setup is incorrect and even if it isn't, need some help understanding how this should work.

The composter came with three trays:

  • two with holes
  • one with a solid bottom and a spigot

Set up one of the trays with holes for the worms - bedding, coir/soil, paper/cardboard scraps, blanket, etc. Set that tray on top of the solid-bottomed tray, which appears to now have castings (dark/black stuff) and some random worms. The third tray is not incorporated. There is a kid on the top tray (the one with the worms in it). No worms have tried to escape and they eat all their food, which we replenish when it's gone.

Is this setup correct? Will the worms move to the bottom tray or stay where they are? Should I anticipate liquid? when should I start harvesting castings?

I have no idea what I'm doing or what to expect and Uncle Jim's website is no help. 😂😩

Found my first set of babies in my bin! Some of them are red with white dots on them. Should I be concerned?

No dead worms & no smell.

Found some babies today when I went to turn my bin and check on everything. A couple of them look like this. I quarantined them for now until I figure out if it’s safe or not.

Aquatic black worm advice?

Hey, I’m not sure if this is the right place to ask this, so forgive me if it’s not.

I culture live food for my fish, including the ones mentioned. They share their tank with ramshorn&bladder snails and Neocaridina shrimp. I have a low level of black diamond blasting sand (1.5cm at most) for substrate and the detritus is building up a lot.

I do weekly maintenance by siphoning the water column with pantyhose over the intake. (To avoid sucking up baby shrimp & ostracods) but I’m stumped as to how I can suck out the gunk without taking a ton of worms with it. Even a gentle stir kicks up tons of worms. Plus when I turkey baster them out for feeding, they roll up into a ball clinging to the detritus thereby fouling whichever tank they go to.

I’d be extremely grateful for ideas or tips on this, tyty.

Casting under microscope

Looking at casting under a Microscope. I am not exactly sure what I am looking at. If someone has a better idea Please let me know I wanted to compare my castings to store bought.

Maze worm farm/counter top bin?

Looking for something that can fit on the (15-inch deep) bar countertop in my apartment kitchen. I'm thinking of getting the Maze composter but all the posts I can find are at least a few years old and don't answer some of the questions I have:

-how much usable space is in each tray(how much compost can it hold?)

-is each tray held up by the one below it or does it just rest on top of the compost? I've used a Worm Factory and the main thing I don't like is that it seems like the contents of the lower trays get compressed really quickly even when the upper trays don't have much in them.

Mold - bait worms

Tried adding horse pellet alfalfa as feed to my bait worm farms. What did I do wrong to cause a mold outbreak? Can I shovel the top layer off, and try and remediate the existing soil and colonies?

Haven’t searched for survivors but each box contained approximately 300 garden worms. Room temps low50-mid 60, don’t have a dedicated bait fridge.

Hummidity sensors are burried under alfalfa.

One mans trash(can) is another mans treasure

Used this mesh trashcan as a sieve for my worm compost. It had a circular mesh of 3 to 4 mm which stops most of the worms (and cocoons i think).

How to you deal with fire ants inside the worm bin? Any safe products to kill them without hurting the worms?

I have 2 Worm Cafés in my bedroom and 1 of them is infested with fire ants... It doesn't seem like they're harming my worms, but I want them gone. I had just put food out for the worms to eat, and their already getting grumpy at me for opening up the lid while they're feasting. Is their anything that I can do to get rid of them without interrupting my worms dinner in the process?

From doing research I heard that you can use Diatomaceous Earth.. does this actually work without harming the worms?

Dead worms?

Brand new to worm composting. My order came from Uncle Jim’s today and based on tracking they rode around town in the cold for eight hours before finally being delivered tonight. I immediately put them in moist soil with kale and strawberries. Some of them revived and are fat and red, but most look like this guy and aren’t moving at all. Like, hundreds of them look like this. Can I expect them to revive within a couple of days, or did I get a bag of dead worms? I feel so bad for them and feel like I did something wrong.

Honey

My red wigglers love lettuce. I am going to mix honey and lettuce in a blender and see how they like it.

Considering jumping in…

So I’ve looked into this off and on for a few years and I think I’m about ready to take the leap, but I have a question or two and check on my knowledge first

https://www.amazon.com/dp/B0BV3H6M6F/?coliid=I2S3E7DAVX5TAE&colid=3UCP54PI37MSP&psc=1&ref_=list_c_wl_ys_dp_it I picked out this kit, I know there are cheaper but this one has great reviews and some been updated over years so I feel confident in it

Yes to put in: -raw or cooked veggies -eggshells -not often but wood shavings/chips(I’m a woodworker) -not often small amounts of grass clippings -cardboard and paper(preferably not heavily dyed or treated paper -fish?(heard mixed things. Mainly thinking like bluegill and crappie remains after filleting) that kit probably isn’t big enough anyway.

No Go’s -anything not organic -meat -oil -veggies or salad greens treated with butter or salad greens -certain types of wood shavings/chips like walnut as they have potentially poisonous compounds in them -anything that hasn’t had soap thoroughly washed off it

Do’s: -freeze and chop veggies -bury any input in the bedding/make sure it’s covered -monitor moisture levels. Don’t let it dry out but not dripping either

Anything I’m missing or got wrong? My main question is which worms. I know red wrigglers are the main but I want something big enough I can use as bait for fishing as well(I want to make myself as self sufficient as I can which for me includes catching as well as growing my own food) Anything I’m forgetting or apparently don’t know?

Wood, Coffee, Grass, and Worms?

So I have this large area in my garden that we're hopefully going to use for gardening In the future.

So I'm kind of using it as a long term soil/compost project. It's a big flat L shaped garden box, probably about 48 sqft.

Currently it's filled basically with only wood chips (from a fresh chip drop), spent coffee grounds, and grass (and urine, I guess).

I already have a worm bin, but I was wondering if I threw some worms into this area, would they survive/eat/reproduce? I would probably cover it (or at least one section) with some cardboard to provide some protection/shade. It's not deep enough to get hot, I don't think. But would the grass/coffee/wood create the microbes the worms need?

New Worm Bin Moisture

I just started a worm bin a week ago in a 17 gal tote with 60 red wigglers. The bedding consists of some dirt, shredded newspaper and cardboard. Along with an old avocado shell found in a garden bin.

Right now I am trying to figure out how much moisture is needed in the bin. It feels damp but no water comes out when I squeeze a section of the bedding. I also live in South Florida and have to keep the bin outside in the shaded patio. Any advice would be helpful, thanks!
