Pre-emergents are best applied typically when soil temperatures reach 55 degrees however the application timing of Prodiamine 65 WDG (Generic Barricade) will vary according to the exact weeds you are targeting and your specific region. We recommend contacting your local extension office to confirm the right application timing for your area. We do have a Lawn Care Schedule on our site with general time frames that may also be helpful.
