I started a new big white bin for my dendro’s or eisenia hortensis

introduction to my new white eisenia hortensis bin

I just started up a new white bin for my dendro’s or eisenia hortensis. At the moment the bin is only filled with bedding and a bit of food.

paper as bedding for vermicomposting

I started up the bin with a bedding of shredded newspaper, some wet cardboard, a bit of compost and a bit of coffee grounds. I know from the past that eisenia hortensis really love cardboard and newspaper. I sometimes even wonder if I really need to feed the worms anything but paper and cardboard.

I did take some bags of frozen food and I spread it over the whole bin. I then covered it up with newspaper bedding so not to get too many fruit flies around.

I amended the bin with lavameal (rockdust) and I will keep this bin without worms for at least another week.

Starting with 200 worms, eisenia hortensis

I plan to start with 200 dendro’s and let the worms fill up the bin with more worms and cocoons. I will take 200 dendro’s from my other white bin so that bin can expand as well.

keep the bin for about 3 months or…

My initial plan was to keep this bin operating for about 3 months before cleaning out the bin and starting with new bedding. But there is a small problem I have to take in account.
It is very well possible that I won’t be able to clean out the bin due to outside temperatures.

I keep my bin in an unheated outhouse. The bin itself is warmed on one side with heating cable so the bedding can’t freeze and kill off my worms. But the temperature in the outhouse can be quite cold and not warm enough to sort the worms.

After calculating the time the bin needs to grow, I found out, it will be the month of octobre before I can sort the worms. In octobre it’s very much possible it’ll be to cold so I’ll have to keep the worms alive in the bin during the winter time. That could take up to 7 months. That means, I’ll have to keep the worms in the bin for 10 months total.

I know the worms and microbes will slow down decomposition in the winter so I should be capable of keeping the worms in the bin for about 10 months. But this also means that the population growth will slow down tremendously.


future plans??

I still don’t really know what I’ll do in the future to keep the worms growing through the winter months. I can ofcourse, like, Bentley, the compost guy says, keep a kind of motherbin inside so I have a small amount of worms still growing through the winter.

I don’t really know what to do, yet. But I’ll find a solution in the near future.


The first white bin is going reasonably well. So, starting up a second bin, is the obvious thing to do.

The second bin will go through winter I think, as I fear the temperature will be too low to remove the worms.

I’m still working really experimentally. I don’t yet have a real “standard” in the way I grow the worms. But we’ll see what the future brings.

That’s it for this message. Thanks for reading and see you in the next post.
