Pre-emergent on hardscapes

[Bunton Guy]

I've got a few clients that are a PITA with hardscape driveways & patios that we can't ever seem to keep up with the weeds growing through the cracks.

Any suggestions for a pre-emergent I can spray?

I was thinking of using :

Resolute Prodiamine 65 WDG Herbicide 5 Lbs Quali-Pro Barricade

[Kelly's Landscaping]

Write off Pre M it stains everything yellow. I think what every you do pick that has to be your top concern is not staining the hardscape.

This will kill any plant it touches. Reapply if need and it should kill any growth for 3 months or longer.

BTW that mix is poison ivy's worst nightmare. I used it on poison ivy in my backyard and it has not grown back ever since that was 2 years ago. Talk about ONE and DONE.
