Importance

The species is the most common weed in Denmark. It is found in all types of crops. In case of dense populations where the plant forms a carpet in the crop, Common Chickweed can cause quite severe losses in all types of crops. In seed fields of White Clovere and small-seed grasses Common Chickweed is an injurious weed because it is difficult to separate the seeds.
