Identify the problem Identify the problem

Grassy weeds are among the most troublesome of all weeds to gardeners, growing unwanted in areas like flower beds, vegetable patches, driveways or paths. Grass weeds can spread easily and are particularly resilient to control.

Grass weeds in lawns are usually courser than the lawn grass and outgrow the fine lawn grasses.

Did You Know Did You Know

  • Grasses are monocotyledonous plants with narrow leaves growing from the base.
  • Couch grass (or twitch) is amongst the most difficult of grass weeds to control because it is good at regrowing rapidly following disturbance and building up food reserves in the rhizomes again, ready for the next disturbance. Although it is found throughout the year, it tends to be less active over winter.
  • Kikuyu is another common grass weed in lawns, flower beds and paths. It also spreads through creeping rhizomes and additionally has stolons (horizontal stems) that root at nodes where they touch the ground.
  • Other common grass weeds include paspalum and poa.
  • Glyphosate, as in Weed Weapon, is the best trans-located herbicide to kill these weeds. It should be applied when each plant has produced at least 3-4 leaves, otherwise sugars may be moving out of the rhizome to help establishment of the leaves, resulting in poor movement of the herbicide to the rhizomes.
