You should probably salute every worm you see. They’re that important. Worms are especially good for the soil and plants.
As worms squirm through the soil, they eat dirt and debris, which then comes out of their back ends. These “castings,” as they’re called, make the soil rich in nutrients (plant food).
But this isn’t the only way worms help the soil. Worms are part of nature’s clean-up crew, devouring dead plant and animal matter in the ground.
Worms also loosen the soil as they dig their tunnels. Plant roots have an easier time growing through loose soil than through very tight soil. In addition, water and oxygen move more easily through loose soil.
Some people are really grossed out by worms. But worms are good friends. They make our soil healthier.
