Biology

Tumblemustard grows 2-5 feet tall. Seedling plants are low-growing rosettes of deeply lobed leaves. Mature plants have stems that are simple below, and many-branched above, providing a bushy appearance. While lower leaves are coarse and divided into broad leaflets, upper leaves are finer with narrow segments. Flowers are small and pale yellow. Fruit are thin 2-valved capsules 2 to 4 inches long. Seeds are small, numerous, yellowish-brown, and oblong with a groove. The plant often breaks off at soil level when mature and spreads its seed while “tumbling” in the wind.

Habitat

A native of Europe, tumble mustard now thrives throughout North America on small grain fields, rangeland, waste areas, and roadsides.

Management Options

Use Integrated Pest Management (IPM) for successful plant problem management.

Non-chemical Management

Select non-chemical management options as your first choice!

  • Not a problem in healthy established turf.
  • Cultivation (rototilling or hoeing) will effectively eliminate plants.
  • Hand-pull to eliminate weeds.
  • Careful digging is useful to manage weed populations. However, digging can carry undesirable weed seed to the surface and foster further germination.

Chemical Management
