We are pulling weeds up by the roots.
Ike's Sandbur and Crabgrass Preventer works only as a pre emergent to prevent weeds from germinating. Pre emergents need to be applied at the correct time in early spring and in late fall for best results. In spring, apply when soil temps rise to 55 degrees and in late fall, apply when soil temps drop down to 70 degrees and continue to drop. Once weeds are actively growing during the summer/warmer months, a post emergent should be used to treat actively growing weeds. In states where soil temps stay warm pretty much year round like Florida, residents use pre emergents on a quarterly basis due to the warmer climate and extended growing seasons. Pre emergent applications during summer months will not harm your turf, we just cannot guarantee any preventative results. If you need to control existing crabgrass in a warm season lawn such as bermuda, centipede, zoysia, or st augustine, you can use a product like Blindside WDG as a spot spray or broadcast application over the lawn.
