Absolutely. Weeds are opportunists. That is to say, that wherever a weak or thin spot in your lawn occurs, weeds will take advantage of that space to move in. The best defense is a good offence. Performing proper cultural practices will strengthen your lawn making it thicker and more resilient over time, effectively crowding weeds out. Water deeply (1/2”) and infrequently, but only water after 7-10 days without rain. Keep your lawn cut at 3-4”. 3” in spring, 4” in summer, then back to 3” in fall. Cutting height will have the biggest impact on the health and density of your lawn. Use compost instead of topsoil when top dressing or seeding. Compost does not contain weeds and comes loaded with microbes and nutrients that will feed the lawn for months and even years. Topsoil is loaded with weeds and has far less nutrient value. Seed as early in spring as possible to beat the weeds. Don’t forget to start the season with a power raking and perform aeration if it’s within your means.
