Onehunga (also known as prickle weed and bindii) is a prickly-seeded weed often found in lawns.
Identify the problem
Onehunga weed, commonly called prickle weed, and bindii in Australia, is a branched prickly-seeded weed that forms in patches up to 40 cm 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.
- Apply LawnPro Turfclean Ultra or LawnPro Prickle and 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 vigorous.
- 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 prickle weed.
- For Dichondra lawns and other non-grass lawns you can spot treat with Weed Weapon Invade Gel.
