General characterisitics
Grow for several seasons from strong underground roots and can regrow from any small segments of root that have been separated from the main plant. Because of this feature perennial weeds cannot be easily composted or chopped up and left in the ground (the more you chop em, the more you make). If you have trouble identifying young perennial weeds from seeds you have planted you could even have a think about sowing a small number of weed seeds in sterile compost early in the season (just so you could recognise your enemy!)

Contributors to this site have advised smothering the couch by sowing rye grass after the ground has been rotavated since rye grass seemed to smother nearly all the perennials.
