Marshmallow (Malva parviflora) also known as Small-Flowered Mallow is a hard to kill annual/biannual weed. It is found on driveways, industrial areas, animal yards, pastures and under trees where livestock congregate.

Marshmallow is difficult to control due to its natural tolerance to glyphosate. It is generally noticed in yards after an area has been sprayed with a knockdown herbicide like glyphosate. Once all the weeds susceptible to glyphosate die off, the marshmallow plants remain, growing back and greening up the area again. If sprayed with glyphosate, the marshmallow may show signs of dying off but from experience it will almost always recover. Below is a photo of this exact situation.

How to kill Marshmallow:

Marshmallow has a natural tolerance to glyphosate and glyphosate on its own is not effective in controlling marshmallow. Weed Force Fang 240 Marshmallow and Nettle Herbicide tank mixed with a knockdown herbicide like glyphosate can improve your control of this troublesome weed.
