My lawn is "Blue Couch" (Digitaria didactyla). It's a pretty hardy grass and tolerates most weed killers that you can use on couch grass (Cynodon dactylon, Bermuda).
What is this creeping weed that is taking over my lawn and how do I kill it? It is aggressive and so low that mowing it achieves nothing.
I'm in Queensland, Australia. Warm climate.
