1. Worm Castings

A compelling reason to start a worm farm is to use worm castings, a natural by-product of vermicomposting.
A compelling reason to start a worm farm is to use worm castings, a natural by-product of vermicomposting.

As worms eat compost, their waste (aka poop) creates an organic form or fertilizer called worm castings. The process of making worm castings is commonly known as vermicomposting or vermiculture. Worm castings are widely regarded as the best fertilizer in the world. Furthermore, worm castings are nutrient rich, help aerate soil, improve drainage and increase water retention.

2. Minimizes Food Waste

Discarding food waste in the garbage is bad for the environment. And don’t forget the huge cost to transport the food waste to landfill. A worm farm recycles food waste and returns the nutrients back to the soil. And the added bonus is your garbage bin will be less full.

3. Worm Tea and Worm Farm Leachate

The excess liquid that is drained from a worm farm tap is called worm farm leachate (worm juice). It's similar to worm tea.
The excess liquid that is drained from a worm farm tap is called worm farm leachate (worm juice). It’s similar to worm tea and as an organic fertilizer, this is a great reason to start a worm farm.

Worm tea is the liquid concentrate of worm compost.  There’s a few different methods how to make worm tea. Worm farm leachate (worm juice) is any excess liquid drained from a worm bin. Both worm tea and worm farm leachate are an excellent fertilizer for your plants and soil.


4. A Fun Hobby

Vermicomposting is a fun process to watch, and can be a great hobby.

5. Easy / Low Maintenance

Anyone can learn how to compost with worms. It’s easy! And once you get going, there’s little or no maintenance involved. Just remember to feed your worms (not too much though!) and watch the conditions in the bin. If you encounter any problems, a few minor tweaks here and will usually fix things.

6. Great for Kids

Kids will love to play with dirt and worms in their habitat. In addition, feeding worms and harvesting the worm tea can also be a great kids activity.

Worm farming also educates children the true nature of recycling.

7. Suitable to Be Kept Anywhere

Worm farms are convenient, space-efficient and clean. Perfect for indoors or outdoors too! For example, you could have a worm farm in your apartment or under your desk at work. I keep mine tucked away near our spare toilet over Summer.

8. Cheap / Free to Get Started

Worm farms have low start up costs. Alternatively, you can create a DIY worm bin on a budget.

Worms are prolific breeders too, meaning you can start small and grow the population.

9. Worms Can Be Used as Fishing Bait

For the fishing enthusiasts, you can use composting worms as fishing bait. African Nightcrawlers are the lagers species for worms and are therefore more popular as fishing bait.

10. Own a Pet

Worm composting allows you to care for thousands of pets. That’s amazing and cool! Although I get sick of my friends asking me whether I’ve named my worms yet…

11. No Bad Smell

Despite the worm poop, rotting food and bacterial decay, a well maintained worm farm should have an earthy smell. Unfortunately, if your worm bin starts to smell rotten and vinegary, then it’s most likely that your worm bin is too acidic.

12. Science

Why not use science as a reason to start a worm farm? Charles Darwin, best known for his theory of evolution, was fascinated with worms. He curiously observed their habits and even published a book with his findings.

13. Make Money

Some people make money by selling compost worms, worm castings and also worm tea (juice).

14. Save Money

If you have worm castings and worm tea, there’s no need to buy any fertilizers, soil conditioners or pesticides.

15. Reduce Greenhouse Gases

A key reason to start a worm farm is because it’s good for the environment. Methane is produced when food breaks down, and is one of the worst greenhouse gases created in landfill. Composting worms reduce the amount of greenhouse gas generated as they transform organic matter into worm castings.

16. Reverse Global Warming

When we burn fossil fuels, we take carbon from the soil and turn it into greenhouse gas. Consequently greenhouse gases causes the atmosphere to heat up.

Worm composting helps add carbon back into soil in the worm of worm castings.

17. Dispose of Dog Poop

Some people use worm farms to transform pet poop into an organic fertilizer. Not a bad idea! Composting dog poo in a worm farm is easy to manage and good for the environment too.

18. Fast Processing

One of the main reasons to start a worm farm instead of a different composting method is it’s speed. Composting worms process organic matter amazing quickly. Worms can digest about half of their body weight on average per day.

  1. If they are eating too slowly, chop up vegetable matter, which is easier for them to eat and gives new meaning to the term fast food. If the chopping doesn t help enough, reduce the amount of organic matter you are feeding them.
