Avoid known individual plant locations and conduct operations elsewhere when they are least likely to cause damage. Ideally, this would involve frozen, snow-covered ground. However, in areas of the state where frozen conditions are unreliable, very dry soils late in the growing season might be the best available alternative. Consult with a biologist, if needed.
Avoid broadcast spraying of herbicides and use care with spot spraying.
Because this plant is an annual, work may safely be conducted before the plants emerge or after they have developed mature seeds.
