Although there are thousands of types of earthworms, the worms that we sell are the Red Worms or Red Wigglers (Eisenia foetida). They are special worms because they prefer the top layer of the soil as opposed to the usual “tunnel-diggers” we have in the garden. They are “compost-making-machines”. They are very sociable creatures so do not mind a big conglomerate of worms. They also eat very fast and a lot so your compost will be produced in 3 months and not 2 years! And they are excellent for fishing too. In order to survive being in the top-soil they breed faster than most other types of worms.
