Weeds are a year-round problem. The two main groups of weeds are grassy weeds and broadleaf weeds. Grassy weeds, which include crab grass and dallis grass, are most common in the spring and summer. Pre-emergent treatment can prevent some, but not all, grassy weeds. Broadleaf weeds, which include thistle and dandelion, are most common in the fall, winter, and spring.
A thick, healthy lawn prevents weeds by starving them of both nutrients and sunlight. In addition, lawn treatment companies often apply pre-emergent to the lawn to stop weeds before they grow, and post-emergent to control weeds already growing. To limit overall stress, post-emergents are used sparingly during summer heat. Knowledge is key to successful weed control. Professional lawn treatment technicians custom design their treatments to address each lawn’s specific problems.
