Buttercup oxalis, a perennial weed, is propagated from nutlets that germinate in fall. This weed is easily spread with planting stock and cultivation. Buttercup oxalis is a contributor to rodent control problems in artichoke as the nutlets are a desirable rodent food. It is very competitive with artichoke, competing for moisture, nutrients, and light.
Black mustard is an annual weed that is very competitive with artichoke in the winter months.
It is also attractive to bees and must be controlled before it blooms and attract bees in order to allow insecticides that are toxic to bees to be used for the control of plume moth. Field bindweed is a vigorous perennial weed that grows either from seed, stolons, rhizomes, or extensive roots. Because seeds can survive up to thirty years in the soil, destroy plants before they can produce seed. The plants may be spread vegetatively through stem or root sections during cultivation. Prevention is the best control.
