Earthworms in Autumn
Autumn may be a worm's favorite season. It's dark, cool, and moist. That's how worms like it. Believe it or not, worms are responsible for eating many of the fallen leaves and debris that result from autumn season. They hang around because there's good stuff to eat, and they like the cool temps and moist conditions of fall. But in late fall, down they go. When temperatures drop or soils get too warm or dry, worms know what to do. If it starts getting chilly, many kinds of worms tunnel deep into the soil before it freezes. Worms "migrate" downward, burrowing deeper to get past the frost. Sometimes they dig six feet deep!
