Coarse Grass in Lawns

Coarse grasses such as Paspalum, Kikuyu, Couch/Twitch, Poa, Barley, in fine turf lawns can be a difficult to control weed as lawn weed killers control broadleaf weeds and usually leave grasses unaffected.

Identify the problem Identify the problem

Coarse grasses that can be weeds in lawns include Paspalum, Couch/twitch, Kikuyu, crabgrass, barley grass, Poa annua, barn grass and others. In general they grow in rosettes and have coarser broader leaves and are often of a different colour and texture to the lawn grass so that they make the lawn appear patchy.

Manual removal is difficult and will leave roots and rhizomes in the ground which may sprout again.

  • Spot treat - Wearing rubber gloves paint Weed Weapon Invade Gel onto the crown of the weed grass (central growing region) and as many leaves of the weed grass as possible. This will kill the grass and its roots.
  • For large problem areas, dig out the worst patches in March/April (adding soil to re-establish the level) and then re-seed with LawnPro Smart Patch Mix or LawnPro Smart Lawn Seed

Did You Know Did You Know

  • Some lawns use coarse grasses (e.g. Kikuyu, couch/twitch, etc) as the lawn grass and in these cases other grasses may be regarded as weeds. The same treatment will work on these weed grasses.
