Choosing the Right Winter Grass Treatment
Winter grass, also called Poa annua, is a grassy weed that commonly forms pale green clumps with prominent seed heads. Choose your treatment according to whether the weeds are already growing or you want to prevent the next generation from establishing.

Winter Grass Control FAQs
Which winter grass products can I use on buffalo lawns?
Amgrow Winter Grass Killer, Campbells Poachek and Spartan include established buffalo turf among their labelled uses. Choose a post-emergent treatment for existing winter grass or Spartan for prevention. Follow the selected product’s application directions, lawn restrictions and timing.
What can I use for winter grass in kikuyu?
Spartan is labelled for pre-emergent winter grass control in established kikuyu lawns. Apply before the weeds germinate; it will not remove an existing infestation. Amgrow Winter Grass Killer and Campbells Poachek are not suitable for kikuyu lawns.
When should I treat winter grass?
Timing depends on the product. Apply pre-emergent treatments before germination, generally in late summer to early autumn. Treat emerged winter grass early with a suitable post-emergent product, preferably before seed heads form. Follow the label for local timing, weather conditions, watering and repeat applications.
