Hairy galinsoga (Galinsoga quadriradiata) is a broadleaf weed that is native to Central Mexico but has been naturalized in many parts of the world, including the United States. Like many weeds, it produces a beautiful flower, but hairy galinsoga is considered an invasive plant in many countries. If left to its own devices it can spread fairly quickly over large areas. It grows well around ditch banks, in open fields and lawn areas.

Characteristics of Hairy Galinsoga

This plant has an erect stem that grows up to 2 feet tall. Leaves of the plant have stems of their own and stick out from the main stem. The leaves are green in color and are egg-shaped and large when the plant is early in development. During growth, the leaves appear smaller and are covered in tiny hairs. When flowers appear, they have small white petals and a round center that is yellow in color. Some flowers may become dull yellow in the center once exposed to sunlight.

Protecting Your Property from Hairy Galinsoga

Even if this weed is pretty to look at, it can cause serious issues if allowed to grow on your property. This plant can grow extremely fast if conditions are right. Hairy galinsoga does well in most soil types and if allowed to establish itself can take over areas of turf. Herbicides and manual pulling are recommended and are effective weed control options. Tillage is also recommended but is less effective when dealing with areas of grass and turf. During tillage, seeds may become spread, which can cause issues the following growing season. General lawn maintenance such as mowing in the summer months will also help to control this weed. To eliminate large invasions of this weed, a professional lawn care service should be consulted. Large turf areas such as golf courses are particularly at risk of becoming victim to this invasive weed.
