Experts and BHG readers answer.
Thanks for writing. Do you spread mulch over the soil? If not, a several-inch-thick layer of mulch should take care of the Queen Anne's lace and most other weeds. You can use just about anything you want as mulch; I love compost because it enriches the soil, but wet newspaper, shredded wood, and virtually any other material that covers the ground should work.
