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 nearly 20 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!

Curtis Windsor’s Trench Vermicomposting Project

I first “met” Curtis Windsor via his involvement in the new (as I type this) VermiGardening Facebook group.

Not long ago I came across a post he had put up about a pretty serious vermicomposting trench project he had launched.

Based on the description and the images shared, I was totally intrigued and I approached Curtis about the possibility of us putting something together for the blog. Thankfully, he was very enthusiastic about the idea, so here we are. 🙂

Below you will find a Q&A session Curtis and I had (in bits and pieces) via email, along with some (more…)

Benefits of Castings & Leachate – 4-10-19


Hello everyone,

The experiment has started! Today is day 0. This morning I prepared all my soils and put them in the pots. The initial plan was to have five soils and five pots of each with three seeds in each pot. But instead of assuming that I would have enough soil for everything, I should have measured it two weeks ago. In the end I had enough soil for 4 pots (and for the leachate part only 3 pots).

The good part is that we can (more…)

Hello everyone,

Myckel (from the Netherlands) here again. If you missed my first post you can read it by clicking the link above.

It’s been about two weeks since I prepared my soils. Now it’s time to continue with starting the experiment. That will be tomorrow, because I will be preparing my seeds first. Seeds will often be put into some water for a day, so that they already can take up the water they need for germination, and get the biochemical processes started in the seed. This often results in a more uniform germination.

The seeds that I will be sowing are (more…)

Walking Windrow Project – 7 Months In


It’s been a “sitting windrow” this past winter, but this baby is nearly ready to start walking again!


Back at the end of August (2018) I started what is easily my largest, most ambitious vermicomposting project to date. At the beginning of July, I had connected with the owner of a 100 acre country property not far from where I live, and he encouraged me to use some of his land to set up worm beds.

As exciting as the idea was – I suspected I would have my work cut out for me (spoiler alert – I DID)!

One of the main goals was to have a large supply of worm castings available for the 2019 growing season. They do a lot of gardening on the property, so I wanted to make sure they were getting something valuable from the arrangement. I knew it would be important to get the ball rolling…and to keep it rolling (at least slowly) during the cold months of winter.

I found a great site for the bed – one that was (more…)

John Kohler vs The Urban Worm Bag

I’ve been a fan of John Kohler – creator/host of the wildly successful “Grow Your Greens” YouTube channel – for several years now. I wouldn’t say I’ve watched “a lot” of his videos – mostly because they tend to be very long – but any time I do, I tend to be drawn in by his contagious enthusiasm about gardening, composting, and various related topics.  I’ve been especially impressed by the amount of air time he gives to the topic of worm composting – and I have little doubt he has been responsible for a lot more people getting interested in this quirky field of endeavor.

With my positive thoughts about John out of the way (haha), (more…)

Measuring the Benefits of Castings & Leachate on Plant Growth

** Guest Post Alert ** – Hi everyone, Bentley here. I just wanted to let you know about a new experiment and blog series being put together by Myckel (from the Netherlands)! This is a topic a lot of people are interested in, and Myckel (as a plant biologist) is just the man for the job. I’m very excited, and appreciative of the time and effort he will be putting into this. Just so you know, Myckel will be added as an RWC author, and all future posts will only have his commentary (if I have comments I will leave them at the bottom like everyone else).

Take it away, Myckel…😉


Last week there was a question here on Red Worm Composting regarding the usefulness of leachate and worm castings for plants. Bentley gave an insightful answer to the question, but the bottom-line is I felt that this actually needs to be tested. As a plant biologist I felt the need to share my view on the topic as well (in the comments section of the post linked above), but it kept me thinking that there is much “copied from others” information and it would be worthwhile to set up an experiment to see and measure how big the advantage (or not) worm castings and leachate have for plant growth.

With spring just started I will be running an experiment to test this and if you would like to join me, feel free to do so, because it would be interesting to see if others can replicate the experiment. I will be giving a description of when I will be doing what and some background information regarding why I do some things the way I do them. If you will replicate the experiment, but change things along the way write them down. You’ll never know if those changes will be important later on.

What are we going to do?

Over the next few months we will (more…)

Leachate vs Castings Tea Revisited

A question from Jae:

I have a question about whether I should really use the worm leachate and worm castings that have been gathering in my farms. A lot of online articles say worm leachate can be damaging for plants while a lot of other people say leachate is actually quite good. Additionally for worm tea, which I gather is made by diluting worm castings with water has to be used immediately. Is worm tea also something that could work for plants and seeing as we have a lot of castings on our hand at the moment, is there a way to store the worm tea without using it immediately?


Hi Jae,
This is something a LOT of people wonder about – largely because of all the conflicting information out there. It is also a prime example of one of those vermicomposting topics where “it depends” is likely the most accurate answer (there are lots of topics like that in vermicomposting – haha).

Let’s start with what I feel is “bad advice” – particularly bothersome since it gets spread around by those who have quite a lot of influence. It’s this idea (more…)
