As the frost sets in, your garden might be dormant, but your worms don’t have to be! Imagine the warmth and energy of a thriving composting system, even in the chilliest months. Winter can be a challenging time for vermicomposters, but with proper care, your worm farm can thrive and keep working its magic year-round. Whether you’re an experienced composter or new to the process, here’s a guide to keeping your worms happy and productive during winter.
Why Winter Worm Care is Crucial
Worms are sensitive to temperature changes. Most composting worms, like red wigglers (Eisenia fetida), prefer a temperature range of 55°F to 77°F. When the mercury drops, they may slow down their composting activity or go dormant. Extreme cold can even be fatal. Protecting your worms during the winter is crucial to maintaining a healthy composting system.
Preparing Your Worm Farm for Winter
1. Relocate Your Bin
Move outdoor bins to a sheltered location such as a garage, basement, or shed. Keeping the bin in a space with stable temperatures will help maintain worm activity. For more tips, check out our winter care guide.
2. Insulating Worm Bins for Winter
Use materials like straw, bubble wrap, or blankets to insulate the bin and retain heat. Consider investing in an insulated worm bin for optimal winter protection.
3. Increase Bedding for Extra Warmth
Add extra bedding material, such as shredded newspaper or coconut coir, to help retain heat and provide additional protection for your worms. This creates a buffer against the cold.
Winter Worm Feeding Tips
Worms’ activity slows in cooler temperatures, so adjust their feeding schedule accordingly:
- Smaller Portions: Feed less frequently to avoid excess food buildup that can lead to odors.
- Chop Food Scraps: Smaller pieces are easier for worms to process in colder conditions. Learn more about feeding worms effectively.
Troubleshooting Winter Challenges
1. How to Handle Frozen Worm Bins
If your bin freezes, don’t panic. Worms can often survive in the unfrozen bedding layers. Once temperatures rise, they’ll resume their activity.
2. Preventing Odors
Avoid overfeeding and maintain proper ventilation to prevent unpleasant smells. If odors persist, read our worm bin troubleshooting guide.
3. Maintaining Moisture Levels
Monitor moisture levels and mist the bedding if it becomes too dry. A well-maintained bin should feel like a wrung-out sponge.
Post-Winter Revival
As spring approaches, gradually move your worm farm back to its regular location. Increase feeding and monitor their activity to ensure a smooth transition. Check out our spring preparation tips for more guidance.

Why every time I click on a subject I get “Opp’s that page can’t be found”?
Thanks for pointing that out Jack! We have fixed the error. Enjoy your reading.
Firstly my thought that is if you guarantee live delivery in the winter, you would ship appropriately.
I’ve wasted way too many pto hours sitting at home waiting for a delivery that arrives dead. For over a month!
Thank you for your feedback. We are very sorry that your packages were delayed and the worms arrived dead. We have had two large snow storms and a Polar Vortex in the last several weeks, and though we have held many orders, some have to be shipped out to customers that need them. We do our best to pack them for the weather, however sometimes, the worms do not make it. We do guarantee a live delivery and will replace them or refund you for them if you prefer. We stand behind our products and our guarantee. Contact our Customer Service Department for any issues, we are happy to make this right.

Would like to see a real size comparison chart on your worms. I know the “Red Wigglers are very small and hard to put on fishing hooks. I am going to need a mix for my lifestyle. RSVP
Hello Rex;
We do not currently have a size comparison chart for our worms. We can tell you that the Red Wigglers and the Indian Blues, in our Composting Worm Mix will get 1-3 inches and the thickness of a spaghetti noodle at full maturity and the European Nightcrawlers will usually get to be 3-5 inches and the not quite the thickness of a pencil at full maturity. The Euro’s are short and fat nightcrawlers.
We do hope this is helpful.

can I mix red wigglers & European nightcrawlers in the same bin
Hello Phillip;
You can raise them both in the same bin together as they like all of the same foods and conditions, however, the nightcrawlers will require more depth to the bin. 10-12 inches of soil in the bin is good for all of the worms. They work different levels so there is a benefit to having both species together.

How can I keep my worm bin warm during the winter?
Hello Talkom; There are many things that you can do to keep the worms alive outdoors during the winter. One way and the easiest, is to move the bin indoors if possible, or you can insulate the bin with many things like insulation, old blankets. straw and rubber or dark plastic tarps. You can bury the bin in the ground and cover it with straw and a tarp or countless other ways. It is all in the imagination.
