Cultural practices

The best defense against weeds is a strong healthy stand of turf. The following cultural practices are ways in which you can improve the health of your turf.

• Fertilize in the fall according to soil tests. During the fall most of the plant’s energy is going to the roots. (put in the fertilizer fact sheet link again)
• Raise the mowing height
• Keep grass as high as you can. Aim for 3 inches or more.
• Never mow off more than 1/3 of the leaf blade.
• Over seed bare areas before weeds can take over
• Use the right turf species for your area. For information about new turf species and their uses, check out the National Turfgrass Evaluation Program.
• Minimize compaction by rotating fields and goal areas whenever possible.
• Aerate in the spring and in the fall to reduce compaction
• When weed seed heads are in bloom, catch clippings when mowing.
• Walk the turf areas frequently and get to know what weeds are present year after year.

Mechanical Practices

• Hand pull weeds whenever possible
• Mulch garden beds and around trees
• Burn weeds along paved areas and sidewalks
• Use steam machines when not aiming for a specific plant.
• Use black plastic to smother weeds in a large area before planting

Best Management Practices for Herbicide Use

• Identify the weed to determine if it is a grass, a sedge, or a broad leaf plant. Determine if it is an annual or perennial.
• Choose the most effective herbicide to reduce the need for repeat applications.
• Apply herbicides when the plant is most vulnerable to reduce the need to repeat applications. Know the plants life cycle.
• Reduce drift by using large droplet sizes and spraying in the evening or morning when wind is low.
• Spray when the plant is actively growing. Drought stressed plants will not take up the herbicide efficiently.
• Water in granules according to label directions
• Use a spreader sticker if the label recommends one
