What cultural practice helps crowd out weeds in turfgrass?

The best choice for helping to crowd out weeds in turfgrass is fertilizing. Fertilization supports the growth and vigor of the desired turfgrass species, enabling them to establish a strong, healthy canopy. This healthy turf can outcompete weeds for essential resources such as sunlight, water, and nutrients, thereby reducing weed infestations.

Frequent watering can sometimes lead to weaker, shallow-rooted turf if not done properly, which can actually make lawns more susceptible to weed invasion. Low mowing, while it can help with certain turf aesthetic aspects, can stress the grass and make it more vulnerable to weeds. Weed removal, on its own, may not effectively prevent future weed growth unless the underlying grass health is also adequately managed through cultural practices like fertilization.

Thus, by ensuring that the turfgrass is well-fertilized, it's possible to foster a robust growth pattern that inhibits weed establishment and proliferation.
