Botanical name: Malva spp.
Common Names
Mallow, Common mallow, Marshmallow weed
Mallow is a common broadleaf weed found throughout Australia, particularly in lawns, garden beds, roadsides, and disturbed soils. It is widespread across Western Australia and is most active during the cooler months, although it can persist year-round in favourable conditions.
Mallow is a low-growing to upright plant that can form dense patches, competing strongly with turf and ornamental plants. It establishes readily from seed and is commonly found in neglected areas, compacted soils, and nutrient-rich sites.
The leaves are round to kidney-shaped with scalloped edges and a slightly crinkled texture. They are typically soft and green, growing alternately along the stems. Mallow produces small flowers that range from white to pale pink or purple, often with darker veins.
This weed has a deep taproot, making it more difficult to remove once established. It spreads primarily by seed, with plants capable of producing large quantities that persist in the soil seed bank, leading to recurring infestations.

SCENARIOS AND SOLUTIONS:
Nutrient-rich soils: Use Apparent Salvo to control actively growing plants before they mature and set seed
Lawns and turf areas: Use a selective broadleaf herbicide such as Apparent Bow and Arrow or Apparent 2,4-D Amine to remove mallow without damaging turf
Compacted soils and along fence lines or edges: Apply Apparent Salvo and improve soil conditions to reduce future establishment. Repeated applications to remove taproot
