Thistles are prickly leaved weeds that will grow in lawns and waste areas of gardens.

Identify the problem Identify the problem

There are several species of thistle that are weeds in New Zealand; nodding thistle, Californian thistle, Scotch thistle and star thistle. Californian thistle is perennial and can be difficult to control due to vegetative growth from its creeping and spreading root system.

In mown lawns it produces flat low leaves in a rosette. As the leaves are prickly they can make walking barefoot or lying on the lawn a painful experience.


In Lawns

  • Apply a selective herbicide like LawnPro Turfclean Ultra or LawnPro Turfclean. This will effectively control thistles but will leave lawn grasses unaffected.
  • Because of the large rosette habit of thistles in lawns they can be easily spot treated with Weed Weapon Invade Gel.
  • For best results use in Spring and Autumn when weeds and turf are growing.
