Tillage can be another control option, but is often expensive and not practical.

Tillage is more common in agricultural areas than in non-crop areas. On occasion, tillage can be used in rangelands, along roadsides, and in utility rights-of-way. Tillage using plows or discs can control annual weeds by burying plant parts. This is more effective on annuals than perennials. In contrast, tillage using harrows, knives, and sweeps can be used to damage root systems or to separate shoots from roots in younger plants, and can also be used to damage roots in larger plants
