How to Kill Love Grass

By Sarah Morse ; Updated September 21, 2017
Love grass originates in South Africa.

Love grass, or lovegrass, comes in many different varieties, most of which are invasive. Love grass grows in light green clumps with stems growing 2 to 5 feet tall. Little flowers produce hundreds of seeds that spread quickly and easily. In order to eradicate love grass, you must be persistent throughout the growing season. A combination of mechanical and chemical methods will kill the grass.

Begin the removal process in late winter or early spring. Wait until after a rain when the ground is soft enough to work. Alternatively, water the love grass an hour or so before you start the removal.

Dig the love grass out of the ground with a shovel. Try to get the entire root system out at this time.

Apply a glyphosate herbicide in spring after the new foliage is fully grown and before blossom heads have formed. Follow the directions on the package for application instructions. The herbicide may kill other plants, so be careful you do not drip or spill on other susceptible plants.

Repeat these steps if the love grass returns the following year. Within one to two years, the love grass should disappear.
