Abundant, vigorous grass overpowers weeds and denies them the nutrients they need to grow. Not only will proper watering choke out existing weeds, but it will also prevent weeds from growing in the future.

What kind of grass will choke out weeds?

Bermuda grass is the best warm-season grass for choking out weeds. Kentucky Bluegrass is the top option for battling weeds in cool-season grass lawns.

Does letting your grass grow long kill weeds?

Longer blades also have more surface area available for photosynthesis, which produces life-giving food and energy for the lawn.
