Grass Clippings – In the Garden

Q: I use grass clippings as mulch in the vegetable garden. Is it OK to use a pre-emergent on my lawn and then put the clippings in the garden?

A: Chemicals used to prevent weeds are designed to dissolve off the grass leaves and then to be absorbed by soil particles. If the pre-emergent has been watered-in by irrigation or rainfall you can use the clippings in your garden.
