Great question from Heidi:
I’ve been keeping worms for about fifteen years or so. When we have gone away our son has fed the worms and I have frozen ‘food’ in preparation for this. This year our son lives too far away to help out. Can you tell me the best way to leave them? I see from an earlier post that you said that you could leave the bins for a couple of months?? I have four healthy bins. They are in our cool basement in Ontario Canada.
The “short answer” and “good news” is that you definitely don’t need to worry! I’ve been demonstrating just how easily you can neglect worm bins in cool Ontario basements for at least as long as you’ve been actively vermicomposting! Hahaha
When all other key factors are looked after (eg. air flow, moisture, temperature), and a system has been getting fed regularly, really all you would need to do is bulk up on bedding (eg shredded cardboard) to ensure their survival. You might add a small amount of “slow food” – materials that are more resistant to break down, but still provide nutrition over time – like bulky chunks of fresh carrot, but moderation is definitely the key.
Just to provide a bit of perspective…
I set up my “Insurance Bin” system back at the end of January, and did not add anything more to it after that. When I checked up on it 6 months later, the worms were perfectly fine (albeit a bit shrunken – lol). I haven’t checked on the bin recently, but I’m virtually positive they are still fine.
I think yours can handle 6 weeks.
Hope this helps!
