Bittercress

This member of the mustard family has a circle of leaves at its base and produces 6” to 8” stems with white flowers. The flowers mature into inch-long seeds that pop off when disturbed. This plant is prolific only in the spring; by summer, it should be no problem.

Prevention
In flower or ornamental plant beds, use a deep organic mulch to reduce their numbers.

Physical control
In late February, before the flowers go to seed, manually pull them or hoe them. If you manually remove them early in the season as soon as they start to grow, the seeds won’t spread and increase the problem
