Worm beds provide an excellent way to compost food waste and create nutrient-rich worm castings for your garden. Here is a comprehensive guide on everything you need to know about constructing and maintaining a productive worm bin.
What is a Worm Bed?
A worm bed, also known as a worm bin or wormery, is a contained system for composting food scraps using red wiggler worms (Eisenia fetida). Worms feed on organic waste and produce castings that are rich in nutrients plants need to thrive. Worm bins allow you to compost indoors, even in small spaces like apartments. The end result is an excellent organic fertilizer and soil amendment.
Benefits of Worm Beds
- Produce nutrient-rich worm castings to fertilize your garden. Worm castings contain nitrogen, phosphorus, potassium, calcium, and magnesium.
- Provide a convenient way to compost indoors year-round.
- Reduce food waste going to landfills. Worms can consume up to half their body weight daily.
- Require little space and maintenance compared to traditional composting.
- Don’t emit odors when maintained properly.
- Create compost and worm tea to boost plant growth.
How to Make a DIY Worm Bin
Making your own wormery is a simple weekend project using common materials. Here are the basic steps:
Choose a Container
- Use a plastic storage bin, wooden box, or metal trash can between 10-20 gallons.
- The bin should be 8-12 inches deep for adequate worm bedding.
- Make sure the container has a lid to contain odors.
- Drill ventilation holes in the lid and sides for air circulation.
Add Bedding
- Use shredded paper, cardboard, coconut coir, peat moss, or leaf litter for bedding.
- Bedding provides moisture retention and aerates the worm bin.
- Fluff up bedding to fill the bin to the top.
Introduce Worms
- Add red wiggler worms, available at bait shops or online.
- Start with 1 lb of worms per 1 sq ft of surface area.
- Gently place worms on top of the bedding.
Feed the Worms
- Bury food scraps like fruit/veg scraps, coffee grounds, and egg shells 2-6 inches deep.
- Provide 3-4 inches of feeding space at a time.
- Rotate feeding areas to evenly distribute castings.
Maintain Ideal Conditions
- Keep bin between 55-77°F and moisture level like a wrung-out sponge.
- Bury any new food under bedding to avoid odors and pests.
- Fluff bedding weekly and remove any moldy spots.
- Harvest finished worm castings every 2-3 months.
And that’s it! Follow these steps to create the ideal worm-friendly environment.
FAQs About Worm Beds
What can I feed worms in my worm bin?
Worms enjoy fruit and vegetable scraps, crushed eggshells, coffee grounds and filters, tea bags, shredded paper/cardboard, and leaf litter. Avoid fat, meat, dairy, citrus, and spicy foods.
How big does a worm bin need to be?
For 1 lb of red wiggler worms, provide a minimum of 1 sq ft of surface area. Bins are commonly between 10-20 gallons. The larger the bin, the more you can compost.
Where should I keep my worm bin?
Worms thrive at 55-77°F, so keep bins indoors in a garage, basement, kitchen, etc. Avoid temperature extremes or direct sun.
How often do I need to feed the worms?
Feed worms gradually, burying new scraps under bedding every 3-7 days. Provide only enough food so that none accumulates.
Why does my worm bin smell bad?
Odors typically mean excess food or moisture. Bury food well under bedding, reduce feeding, and add more dry bedding to soak up moisture.

Look for rich, dark worm castings with little original bedding left. Harvest every 2-4 months by moving worms to a new bin.
Can I use worm castings directly in my garden?
Absolutely! Worm castings contain nutrients plants need. Mix castings into potting soil or sprinkle onto the garden bed as an organic fertilizer.
Conclusion
Creating and maintaining a worm composting bin is an excellent way to reduce food waste while generating nutritious worm castings for your indoor and outdoor plants. Follow the simple steps above to construct a DIY wormery and enjoy the gardening benefits of vermicomposting. Worm bins require minimal daily maintenance to thrive and provide a sustainable way to boost your garden’s health.
