There are many supply companies that will help aspiring worm farmers get into this business. Obviously, no investment should be made until the company and equipment have been completely researched and marketing claims have been verified. Here are some other delicious thoughts about earth worms. First, they need to remain slimy to breathe. They breathe through their skin and if they dry up, they can suffocate.
Worms create little tunnels.
The tunnels keep them cool during the day. Worms do not like to surface during the day unless it is raining. The tunnels not only help the worms, but they also serve as rainwater and nutrient channels for nearby vegetation. When it rains, worms often leave their tunnels and travel on the earth's surface. When the worms surface, they need to retreat below before the rain ends and the sun reappears.
