WOW!^® Supreme Pre-Emergent Weed Killer and Lawn Fertilizer

WOW!^® Supreme works below the surface of the soil to prevent weeds, targeting them during germination. It's a favorite among the gardeners in our research garden—and it's also one of your favorites, since WOW! Supreme is our best-selling all-natural herbicide! In addition to controlling weeds like crabgrass and dandelion, this formula also contains an all-natural fertilizer for a healthier, greener, lusher lawn. The cool weather in spring and fall creates prime germination conditions for perennial, broadleaf, and grassy weeds, so application at the beginning of these periods is critical. Apply any time after the season's first mowing, 4-6 weeks after seeding, or in springtime when forsythias begin blooming. Apply a fall application anytime from mid-August until the first freezes.
