Onehunga Weed

Onehunga (also known as prickle weed and bindii) is a prickly-seeded weed found in lawns.

Identifying

Onehunga weed, commonly called prickle weed, and bindii in Australia, is a branched prickly-seeded weed that forms in patches up to 40cm across in lawns, playing fields and golf courses.

It is a very unpleasant weed in lawns and turf due to the prickles on its ripe seeds which make walking or lying on the lawn painful.

Solving

In Lawns

Apply LawnPro Hydrocotyle . It effectively kills onehunga weed but leaves your lawn grasses unaffected. Allow 2-3 weeks for prickle weeds to die.

Optimum control is achieved in Spring, Summer and Autumn when weed and lawn growth is vigourous.

For situations where prickle weed or hydrocotyle predominate, undertake soil management at the same time – both prickle weeds and hydrocotyle prefer sour acidic (i.e. low soil pH) and poorly draining soil. Apply 100 g/m2 of lime two weeks prior to spraying. Also consider improving drainage, removing shade or aerating the soil to make the area less suitable for these weeds.

Note: LawnPro Turfclean will also effectively control prickleweed.

For Dichondra lawns and other non-grass lawns you can spot treat with Weed Weapon Direct Hit.

In Flower Beds and Waste Places

Apply Weed Weapon Rapid Action or Weed Weapon Direct Hit .
