How do you eliminate spiderwort?

Cutting to the ground (after removing spent blossoms and once leaves decline) before solarizing and tilling prefatory to replanting with drought-tolerant covers or vegetation is a way to eliminate spiderwort. The (usually purple) flowering plant in question (Tradescantia spp) requires a moist soil so diverting rainfall and monitoring irrigation to dry the patch out will stress spiderwort, as will repeated harvesting for edible, salad-ready foliage. It will be important on the way to eradication to remove all spent blooms immediately since spiderwort seeds prolifically.
