11. Worm Farm
You can combine your compost sales with a worm farm and make money with both. Do you know that Vermicomposting is simply composting with earthworms.
Earthworms helps speed up the composting process and also enhance the finished compost with nutrients and enzymes from their digestive tracts. So, that makes the composting material turns out to be richer and more sought after, thus you can sell it for a bit more.
You get to add to your income by selling the worms during the summer for fishing season, to other gardeners, or to pet owners. Also, how much you can make depends on the breed of worm – as red worms can go for $3 for 100 worms, and nightcrawlers can go for about $30 a pound.
The beauty is that you don’t even need a worm farm to sell worms either, go out after a rainfall and pick them off the ground or go into the forest and dig for them – instant cash.
