A distressing Question of the Day from the Old Farmer’s Almanac about how to rid the lawn of angleworms. (“Angleworms” is another word for terrestrial earthworms.)
The Almanac suggests pouring soapy water into the grass. What???
Folks, earthworms are good for the lawn. Set the blade higher and let the grass grow a little taller. That will conserve water, let roots grow deeper, and make it easier to mow even if there are some worm castings in the grass.
