The answer to 'best weed control' is to use a combination of preventative measures and targeted treatments. The most effective approach is to create an environment that is inhospitable to weeds, while also addressing any existing weed problems with selective herbicides or manual removal.
Preventative measures include maintaining a healthy, dense lawn through proper mowing, watering, and fertilization. This helps grass outcompete weeds for resources. You can also use pre-emergent herbicides in early spring to prevent annual weeds from germinating. For existing weeds, spot-treat with post-emergent herbicides or manually pull them, making sure to remove the entire root system.
