What is a teasel?

Most often seen on roadsides and waste areas, teasel also invades agricultural fields and pastures. It is often spread by the practice of mowing standing plants after they have formed seeds.

How many seeds does a teasel plant have?

How to control teasel?

Fortunately, teasel is not that difficult to control, especially if you can catch it while the population is small. Individual plants can simply be dug up just like a large dandelion. Several herbicides have been shown to work on rosettes and pre-flowering plants. Please contact our office or refer to the PNW Weed Management Handbook for more information on effective and safe use of herbicides. Mechanical control is also effective if done correctly. Once the flowering stalks form, wait until the flowers start to appear and then cut the plants at or right below ground level with a machete or sharp shovel. Mowing is not as effective because plants can re-grow from the root crown if they are cut too high. If a mower is used, set it as low as possible and check back for any re-sprouting plants. Teasel plants that are knocked over by the mower or cut too high will probably be able to re-grow and set seed. Also, it is best to remove the flower heads and dispose of them because immature heads have been known to set seed if they are left on the ground. And, of course, if you do mow mature or standing dead teasel, make sure to clean off your equipment before leaving the site to avoid spreading it. For more detailed information on control, follow the links before for additional information or contact your local county noxious weed program or extension office.

How long does it take for a teasel to grow?

Common teasel can grow as a biennial meaning it spends one year as a rosette followed by flowering, or as a macrocarpic perennial, meaning that it grows as a rosette for more than one season until it builds up enough resources to flower and set seed. Common teasel produces a deep taproot, up to 2 feet long and an inch wide at the crown. Plants generally die after they set seed and reproduction is entirely by seed. A single head produces on average 850 seeds and a plant can have between 1 and 40 flower heads, or as many as 34,000 seeds per plant. Most seeds fall near the parent plant but they are often moved to new locations by water, soil movement, mowers, animals or other means.
