Wireweed is a summer annual which establishes very early in Spring, expecially in wetter soil. It establishes well in bare soil, and is very tollerant of tredding, making it a common sight around farm gates and paths
It ranges from a sprawling plant with small leaves when growing on bare/trodden ground, or a leafy upright when growing in crops.
It is well controlled by herbicides, although best in the early seedling stage.
