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.
Lawn Weed Control
In lawns, fall is the best time to chemically control broadleaf perennial weeds. Examples of these weeds could include dandelions, Canada thistle, creeping bellflower, field bindweed and ground ivy.
Overseeding your lawn is a smart maintenance procedure and a great way to renew your lawn after periods of drought. Fall timing gives you the best conditions for new grass to grow and thrive.
Garden and lawn issues can sometimes be diagnosed by simply looking at a photo. Photos give our Extension experts a place to start, and providing them with the best possible photo can help the process.
