Can I Compost Grass Clippings After Treating Lawn with Herbicide?

Question:

I recently treated my lawn with a broadleaf herbicide. Can I place grass clippings in the compost pile?

Answer:

Herbicide residues should not be a problem if the grass clippings are thoroughly composted. As an added safety measure, mow the lawn two or three times before collecting and adding the clippings to the compost pile.
