Broad-leaved Dock
Broad-leaved Dock
New Zealand hosts a variety of species of dock and Broadleaf Dock would be the easiest to identify for most people as it is the most common.
It’s a perennial weed with large broad leaves and a thick, strong taproot.
It’s known to survive in regularly mown lawns by producing small leaves. Left to its own devices, it can grow up to 1 metre tall when flowering.
Control
Herbicides containing a mixture of Triclopyr and Picloram will be effective (Victory Gold, Triumph Gold, Tordon Gold or Conquest).
