sorry for bad image quality, but i have been tasked with removing all of these such weeds from our lawn, as come summer they dry and stick into your feet.
what would be the best way to take care of these, and to ensure they dont return next growing season?

Hi Tim

The success of removing these weeds should be approached over a period of months unless you are prepared to kill off all the lawn and weeds with a general non-selective weed killer like Kiwicare Organic Weed control and relay a new lawn by seed or with ready-lawn. The benefit of this is that the solution is organic; however another option would be chemical control as outlined below with a feed then weed-and-feed program.

Because your lawn is so greatly affected and it is a weed that will keep spreading; it is ideal to work with firstly feeding your lawn in Autumn (April) and then again in early Spring (early September) and then by this stage the grass that is present will be strong and very healthy for you to spray with a weed and feed product by Yates in October. One week after spraying with this product; apply spray for Onehunga weed control (prickles). Yates have a product called ‘Yates Prickle Weed Killer’ that is effective control for this. In November you will have a good idea of what actual healthy grass you have left. Use a stiff rake to remove the dead weeds and then oversow with fresh lawn seed as per the manufacturers recommendations.

Water your new lawn seeded area for 10 mins morning and night and be sure to string up reflective tape crossways over the lawn area to prevent birds from stealing your seed.

In the future keep your lawn mowed at a 8cm height every week in the growing season of Spring and every 3 weeks in the height of summer. A thick and healthy lawn will reduce the chance of weeds taking control again in the future.

Best of luck
