In strawberries, the lack of tillage at these times and winter protection with mulch allows these weeds to survive and thrive. Renovation does not affect these weeds, as they have generally produced seeds by July. Both common and mouse-ear chickweed are in the Caryophyllaceae, or 'pink' family. Well-known plants in this family include garden flowers such as carnations, Dianthus and Maltese cross. Other weeds in this family include mouse-ear chickweed, white cockle, and knawel.
Common chickweed is edible, and leaves can be added to salads.
Because common chickweed is low growing and shallow rooted, its ability to compete with strawberries is limited. If chickweed is left uncontrolled for many years, populations can build up to the point where yields are impacted. When common chickweed is present in great numbers, lower leaves of strawberry plants can be shaded. In addition, heavy infestations of this weed could block air flow around strawberry plants, increasing the likelihood of fungal disease problems. 4-D is not effective on this weed.
