I live in Charlotte, NC. and the soil is heavy clay. I have a 1200 sq. ft. front lawn and a 3000 sq. ft. rear lawn. I want to know how many worms, and what type of worm, I should buy to help with aeration and soil conditioning. I have read that worms for the lawn become a nightmare to control, and I will wind up with a problem eventually, due to castings making the lawn slippery and muddy.
