Earthworms are not only happy to burrow in the dirt of your garden, they're also incredibly useful — they improve the fertility of soil by converting its organic matter to humus, which helps plants grow.

They may not be pretty, but earthworms are very helpful. WORD FAMILYearthworm: earthworms USAGE EXAMPLES‘It is like an earthworm trying to communicate with a buffalo.
