Lawn Weed Control

Cultural weed control practices must be included in weed management programs to optimize control and inhibit re-infestation. A healthy, dense turf cover is the best overall defense against weed invasion. Some common cultural weed control practices include planting the most adapted turfgrass species for your environment (i.e. shade, full sun, or hot, dry conditions), maintaining a mowing height of 2.5–3.5 inches, watering deeply but less frequently, and proper soil maintenance including fertilization and core aerification.
