- Mow as high as practical during the summer months.
- Mow often enough so that no more than one-third of the grass blade is removed in a single mowing.
- Irrigate properly to help reduce annual weed infestation.
- Fertilize according to the needs of your grass species.
- Aerate the turf at least once a year to reduce compaction and control thatch.
- Mulch with organic or inorganic materials to prevent annual weeds.
- Prune or remove flower heads of weeds to limit seed production in April for winter annual and summer for summer annuals.
- Remove annual weeds by hand. Hand removal of perennial is seldom effective.
- Time cultivation based on pulses of weed seed germination and growth and the time of crop emergence.
- Use propane flame-burners during times of high field moisture.
- Apply natural and synthetic mulches.
- Adjust seeding date to allow quicker emergence and a more competitive crop.
- Plant at the maximum adapted population using seeds with a high germination rate.
- Quick canopy-forming varieties help the crop competitiveness over weeds within and between rows.
In forests and rangeland:
- Use weed-seed free hay, feed grain, straw and mulch
- Do not drive vehicles through weed infestations.
- Manage desirable vegetation to be competitive with weeds.
- Detect and eradicate new introductions with herbicides.

- Seed with desirable plants if necessary.
