The answer to 'how often to weed control' is that most experts recommend applying weed control treatments 2-3 times per year for optimal results. This helps prevent weeds from taking over your lawn and landscape beds. The first application should be in early spring, followed by another in late spring or early summer, and a final treatment in late summer or early fall.
Applying weed control on this schedule will keep your yard looking its best by stopping weeds from germinating and spreading. Be sure to follow the product instructions carefully, and consider hiring a professional landscaper if you have a large area to maintain or are unsure about proper application.
