Annual Poa

Garden Problems , Lawn Problems

Annual meadow grass (Poa annua) is a common weedy grass in New Zealand gardens and lawns.

Identify the problem
Poa can look like other turf grasses in lawns. It is often a lighter green than the lawn grass. It is also a common weed in waste places, flowerbeds and paths.
How to solve the problem
Lawns
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
Flowerbeds
- Spot treat - Wearing rubber gloves paint Weed Weapon Invade Gel onto as many leaves of the Poa as possible. This treatment will kill the grass and its roots without risk to surrounding plants.
- Follow up with Weed Weapon Preventer sprinkled in the flower bed to prevent new weeds emerging.
Paths, Driveways etc.
- Apply Weed Weapon Long Term to kill existing Poa to the roots and prevent new growth appearing for an extended period.
Waste Places
- Apply Weed Weapon Extra Strength or Rapid Action for rapid killing of Poa to the roots.
