Answer: Many turfgrasses, such as Bermuda, have tenacious and invasive root systems that can live to spread in your garden soil. The tiniest piece of root tissue can live and spread. If you create "hot" compost piles that reach temperatures of 140-160 degrees F for several days, they can kill the roots. Otherwise, I wouldn't recommend it. Knock the soil off into the compost pile, but don't put the roots in.
