Giant Hogweed (Asclepias tuberosa) is a weed that grows in many parts of the world. It is native to Europe and Asia.
Giant hogweed has become invasive in North America due to its ability to grow quickly and take over a lawn with little effort. Giant hogweed produces large, greenish-yellow flowers that bloom profusely during late summer through early fall. The plant spreads rapidly throughout the lawn and takes over within a few weeks. Its leaves are hairy and it produces small white seeds that germinate readily when disturbed.
Invasive species are often difficult to eradicate because they reproduce so fast and spread so widely. They may even outcompete native plants in their new areas of distribution, creating problems for future generations of native plants.
Some invasive species have become established in places where no other plants exist, such as deserts or mountain ranges. Some invasive species have even blocked rivers and streams.
Hogweed can be a problem in lawns and gardens by creating unsightly patches of green amidst the greener, more manicured lawns. This noxious weed can also create problems for farmers and farm animals.
It can take over fields and pastures, serving as an unsuitable food source for grazing livestock.
Giant hogweed is a broadleaf evergreen that can survive many common herbicides and pesticides. Many attempts have been made to control the spread of giant hogweed in areas where it has become invasive.
None of these attempts have succeeded, at least not without the aid of human machinery.
Giant hogweed is one of the most difficult weeds to eliminate because weed whackers cannot kill it without destroying a lawnmower’s cutting blades. Even a few dead leaves or seeds left behind can regenerate giant hogweed to full size within a few weeks.
Giant hogweed has a long taproot that runs deep into the soil. This taproot makes it difficult to eliminate by pulling it out of the ground.
Giant hogweed is nearly impossible to kill with herbicides or pesticides. Most herbicides are only effective for a few hours after application and most pesticides do not work at all on giant hogweed.
Cultivation of giant hogweed can be prevented by removing its flowers before they can produce viable seeds. Hand-removing all of the flowers is one way to prevent this noxious weed from reproducing.
Giant hogweed can be manually killed by cutting the vegetation at the base when the plant is smaller. All vegetation must be removed, including the taproot.
All parts of the plant must be disposed of carefully so that no pieces are left behind to regenerate into new plants.
Giant hogweed can be prevented by minimizing disturbance to the soil. Sites that are prone to giant hogweed infestation include construction zones, empty lots, and areas along rivers and streams where soil is easily disturbed.
Giant hogweed can spread by releasing its seeds into the wind. These seeds can be carried for miles away from the parent plant.
Wild animals such as birds and deer often carry these seeds even farther.
Giant hogweed can also spread through its roots.
