How do I get rid of bishop weed?

Bishop weed is a difficult perennial weed to control because it can regenerate from portions of the plant, including pieces of its root system, so repeated pulling may not provide lasting control. One option is to cut the foliage back and apply a concentrated systemic herbicide such as glyphosate to the freshly cut stems, allowing the herbicide to move into the roots. For larger infestations, another approach is to cut the plants back, treat the remaining stumps, and cover the area with black plastic topped with mulch for about a year to smother any remaining growth. Patience and persistence are important when dealing with bishop weed, as it can be an aggressive spreader. Gardeners should also be cautious when purchasing cultivated, variegated forms of bishop weed from garden centers, since these plants can escape cultivation and spread into areas where they are not wanted.
