Broad-leaved Dock

Rumex obtusifolius

Key Statistics
  • Broad-leaved dock is one of the five most worldwide spread weeds
  • 80% of all herbicides in Central Europe are used against broad-leaved dock
  • Broad-leaved docks cover over 5% of 10-15% of plots in England and Brittany

Broad-leaved docks are particularly tough for several reasons:

  • Their relatively long cycle is perfect for settling in plots with late mowing or organic crops
  • Its multiple flowering lead to the production of several tens of thousands of seeds per year
  • Its seeds, once buried, remain alive for decades.
  • It is able to regenerate even from small fragments of root
  • Its roots are able to separate after twelve months, leading to new plants, and thus an expansion of the covered area, even in already closed plots.


The presence of broad-leaved docks in a plot leads to reduction in quantity of produced forage and also to a lower quality, in terms of digestibility and palatability. It is one of the main obstacles for establishment of organic crops.
