Red Worm Composting – Welcome!

For those of you who don’t know me, my name is Bentley (“Compost Guy”) Christie and I’ve been a crazed worm composting fanatic (or “vermiholic” if you prefer) for more than 15 yrs now. I started this website back in 2007 with the simple intention of sharing my passion with the world. So far so good! Things have certainly progressed since the early days, though, and the website has provided me with an amazing opportunity to get to know a LOT of other “worm heads” from across North America and around the world!

Crazy Q&A Podcasts – Session #14

I know things have been extremely quiet on the blog this year, but I want to make it clear that I haven’t “moved on” from Red Worm Composting (and certainly not from worm composting in general). I’ve simply been busy with other (related and unrelated) projects…and good ol’ life in general!

And what better way to (hopefully) get back into the swing of things than with a “Crazy Q&A Podcast”?

As some of you will know, I started up a brand new email list, and I asked subscribers to submit questions and topic suggestions.

I decided on the podcast format for my responses since they are (more…)

New to Vermicomposting Trenches

Question from Alicia:

I am a newbie, but have had a great time with my container worm farm.
This season means more organic materials for me, specifically watermelons which I did not like in my bin.

So, I dug a hole, put down a ton of bedding, dumped in the rinds, and added a couple of handfulls of material and worms to the mix after your inspirational trench farm method.

However, after re reading the post, I am worried that my worms will need follow up feeding.

Have I just sentenced my worms to death?

Thanks for the great info.

Hi Alicia,

Your methods sound pretty good to me, especially if you made sure that the bedding materials were nice and moist. Food wastes like watermelon rinds are a great choice since they will help to maintain moisture levels – something that can be a challenge during summer months.

Based on your wording, I get the impression that you (more…)

Garden Worm Help

Question from Abbie:

Hi. I have an indoor garden/greenhouse where turtles and frogs roam
freely through a small vegetable garden. I need worms for the soil.
When I planted this spring I realized that I have no worms in my soil
and it is hard and compacted so I would like to add worms. Any
recommendations or thoughts would be greatly appreciated.

Hi Abbie,

You are certainly not alone in wondering about this topic. It is widely known that earthworms can mix and enrich the soil, so naturally a LOT of people feel the urge to stock their own soil with gobs of worms.

Unfortunately, this is a “chicken/egg” problem that most people get backwards.

Earthworms don’t magically turn any soil into black gold. In fact, if you try to stock worms in lifeless soil, you’ll likely end up with a lot of dead worms and/or a mass migration of the wigglers in an attempt to find ‘greener pastures’ (assuming conditions are favorable for such migration).

This is even worse if you try to (more…)

Extreme Vermicomposting


Likely one of the most common reader questions/concerns over the years has related to the challenge of vermicomposting outdoors (or at least in locations that are not climate-controlled).

While I like to think of vermicomposting as the “ultimate” indoor composting method, I know all too well that keeping worm bins indoors is not always an option – whether it’s due to spousal pressure, space issues, personal preference, or one of countless other reasons, sometimes we simply have no option other than setting up our systems outside.

Naturally, in a lot of locations it can be a major challenge to maintain these systems for at least part of the year. In these cases, our only choices are: 1) to throw in the towel, 2) to bring some or all of our worms indoors, or 3) to get creative with our strategies!

For quite some time I’ve been meaning to put together some information on this topic, and late last fall I finally dove in and started creating what has become the “Extreme Vermicomposting” course.

Catching Wild Red Worms?

Message from Joel:

Hello, I was on a forum and saw a vermicomposting question. They wanted to catch earthworms to use in their vermicomposting. I referred them to your site and suggested the purchase their first batch.

One poster suggested just setting up a pile of leaves and scraps and catching wild red wrigglers. This got me thinking.

Being primarily a compost worm and with us not having lines of compost from coast to coast for them to travel in, how likely would it be for someone to “catch” any red wrigglers this way.

Also, my though was what are the chances of getting some worms or eggs if you went to a big box and bought a bag of organic compost and added to the bin. I’d think you’d have issues with the bag getting too hot and killing them, but I didn’t know if you’d ever experimented with this or possible the same idea, but straight from a whole seller.

Hi Joel,
These are some great questions!
There really isn’t such a thing as a “wild” Red Worm – well, at least not the type of “Red Worm” we are after. Eisenia fetida/andrei worms are very closely associated with human activities, most often being found on farms (in old manure piles) or in compost heaps/bins within town/city limits.

Another type of “Red Worm”, Lumbricus rubellus IS more of a “wild worm”, and there is a pretty good chance you could attract them with a heap of old leaves (assuming they are found in your region) – but they are NOT an ideal worm for vermicomposting. They don’t reproduce nearly as rapidly as Eisenia fetida/andrei, they’re not as well-suited for processing rich organic waste materials, and they don’t have the same sort of tolerance for hot temperatures and crowded conditions as Eisenia worms (although they are much better suited than typical garden/lawn worms).

The other potential “problem” with L. rubellus is that it (more…)

Pencil Shavings in Worm Bins?

This is an interesting question:

I have prepared my first worm bins in anticipation of receiving my first ever order of worms later this week. I am also now on the lookout for any and all items the worms might like. One item I haven’t found mentioned on your site: household amounts of pencil shavings?

Thank you for your excellent website.


Hi Justina,
Generally speaking, woody materials are not the best food/bedding for worm bins since they can take quite some time to fully break down (but they can simply be screened and added to new systems as a “living material” over and over again). That being said, shavings like that are certainly better than chunks of wood or even wood chips.

Although we still use the term “lead”, the actual metal lead probably hasn’t been used to write for hundreds of years (but I’m not a writing historian so don’t quote me on that! lol). The graphite that IS used is totally harmless (and whadya know – it’s a carbon source too!). I would imagine that the core of coloring pencils would be equally benign.

Red Worms At Work

RWC Reader Tara H. recently wrote in to let me know about a cool article (on the “Rodale’s Organic Life” website) that included the video above. It features time lapse photographs (every 10 minutes!!) of an experimental vermicomposting system over the course of 20 days! Really cool.

Be sure to check out the original article for an interview with the people who created the video:

Thanks Tara!
