Marshmallow is a semi upright weed that becomes more erect as it matures. It is characterised by rounded, wrinkled leaves with prominent veins, each consisting of 5–7 toothed sections. The plant stems are covered in stiff hairs, and produce pale pink or white flowers with 5 petals each, growing in small clusters in leaf forks or on the stalks.
Marshmallow can be physically removed in small patches, especially when the plant is young and has a shallow root system. It is recommended for well-established or extensive infestations Starane™ Advanced used at 3mL/1L of water, or Hotshot™ used at 7mL/1L of water.
Cultivation is an effective control method for small to medium sized infestations, however this process is less economic for large or well-established infestations.
