The winter weed sneak attack (and how to beat it)
They’re small, sneaky and spreading fast – and now’s the very best time to control them.
Winter is your best shot to stop them before they take over paddocks, gardens and everything in between.
Winter weeds: small now, serious later
The Northern and Yorke Landscape Board says now is the smartest time to act – before weeds establish deep roots or set seed.
Across the Northern and Yorke district, landholders and home gardeners are being encouraged to act early to get on top of invasive plants before they surge.
“Fresh growth makes weeds easier to control, and acting now is far simpler than dealing with a full-blown infestation later – whether you’re managing a broadacre property or a backyard.
“I’m often asked why we are out there shouting from the rooftops about the importance winter control, and the three biggest reasons which come to mind are:
- Easier to spot – fresh growth stands out after autumn rains
- Easier to control – younger plants means less effort
- Prevent the blowout – stop them now before spring growth and seed set.”
So – what should you be watching for around the Northern and Yorke region?
Among the usual suspects is horehound – the “Velcro villain”– already popping up across paddocks, roadsides and neglected garden corners. Its prickly burrs hitch rides on pets, clothing and livestock, spreading quickly and reducing pasture quality.
Wild artichoke is another to watch. While it might look striking, its spiny leaves quickly form dense thickets that crowd out pasture and garden plants. Acting now helps prevent a huge flush of seeds later.
And then there’s African boxthorn – the ultimate spiky squatter. Found everywhere from fence lines to backyards, it forms dense, impenetrable thickets that harbour pests and thrive in tough conditions.
The key? Start small and start early
“Checking fence lines, creek beds, garden beds, driveways and roadsides now can save significant time, cost and effort down the track,” says Mr Pook.
“Just as importantly, we want to stop weeds moving between properties, so good hygiene– cleaning down machinery, tools, boots and vehicles– can help stop the spread.”
For agriculture alone, weeds cost Australia around $4–5 billion each year in control and lost production. They compete with crops and pasture for moisture and nutrients, reduce land value and, in some cases, are toxic to people, livestock and animals.
“Winter is one of the most important times of year because when spring arrives, weeds won’t wait– and we can’t afford to either,” Mr Pook says.
