Mowing can provide control of tall growing weeds and at least prevent them from producing seed. Mowing is most effective when used in conjunction with a competitive sod or forage crop. Species with growing points near the soil surface are not controlled effectively by mowing. Mowing after pollination has limited to no adverse effect on seed production. Four to six mowing trips per year to control weeds well enough to meet Indiana weed laws and requirements.
Mulches control weeds by excluding light.
Appropriate on small areas and on high value crops Best suited to emerged, established, or transplanted crops. In permanent plantings, plastic mulch frequently is used under a decorative particulate mulch.
