Can Weed Free Zone be used to treat a rock garden to prevent weeds from growing, not just kill existing weeds

I have a large rock area that I would like to spray to prevent new weeds from growing. I understand the product is used to kill existing weeds but want to know if I can used it to prevent new weed growth by spraying my rock areas.


The Fertilome Weed Free Zone is only a post emergent herbicide and will only kill existing weeds.  It will not prevent any from growing. Surlan is our most popular pre-emergent product for rock landscapes.
