Weeds can take over our lawn in the worst way and make them look sloppy. The weeds are sucking up important moisture that your lawn or plants need to fuel themselves. Each weed is different, so we pride ourselves on knowing each weed type and how to tackle the toughest of weeds. Upon application, you should start to see signs of distress within 5-7 days and complete elimination of broadleaf weeds within 2 weeks.
