“You are just creating a lovely environment for serrated tussock by spraying chemicals on it.” Martin Royds said on the Soils for Life Field Day.
The value of Weeds: Thistles
If you have a paddock full of thistles how do you reclaim that land?
Indeed! Treat the cause, not the sypmtom. Create an environment for the plants you want to thrive rather than focusing on what you want to remove. Improve your soil fertility and encourage regeneration of native perennials.
