Couch Twitch Grass
Couch (NI) or Twitch (SI) grass is a common weed in garden lawns, flowerbeds, paths and waste places.
Couch/Twitch grass looks like just a tuft of any grass, but below ground the roots form a dense network. It spreads quickly by means of thin, wire-like, pointed rhizomes.
From root tips, new shoots are produced in spring and autumn that rapidly produce tufts of leaves and more rhizomes.
Manual removal is difficult and will leave roots and rhizomes in the ground which will sprout again.
- Spot treat - Wearing rubber gloves paint Weed Weapon Invade Gel onto as many leaves of the Couch/Twitch as possible. This will kill the grass and its roots.
