Cultivation Details:
Couch grass can succeed in any soil, though it grows best in light sandy soils[238]. It is a rapidly spreading, persistent and pernicious weed that should only be introduced with great caution. It tolerates a pH in the range 4.2 to 8.3.
A food plant for the caterpillars of many butterfly and moth species.
This species can become a pernicious weed, spreading rapidly by underground rhizomes[4] and quickly forming a dense mat of roots in the soil that strangles other plant growth[K]. Even the smallest fragment of root is capable of regenerating into a new plant, thus making it exceedingly difficult to get rid of. A good thick mulch through which nothing can grow, can be applied to the area, though it will need to be left in place for at least two growing seasons to be fully effective[K]. Despite its antisocial tendency in the garden, couch is a very useful herbal medicine and Culpepper is said to have stated that half an acre of couch was worth five acres of carrots twice over[4].

Propagation Notes:
This species is a pernicious weed and will not require assistance in spreading itself.
