  1. Hi
    I have a fantastic sir Walter lawn thanks to Jimboomba turf, free of any issues. Unfortunately I had to lawn an adjoining section (20m2) and purchased the ‘sir Walter’ from Bunnings. There appears to be couch or kikuyu? Starting to overtake the sir Walter in a few places and it’s progressing quickly. Is there anything that can be fine to save the sir Walter from being totally overtaken? Can you use fusilade to kill the couch, will this also kill the sir Walter? Someone also suggested vinegar will kill couch but not harm sir Walter? Love to hear your suggestions.

      Hi Rick,

      Couch is notoriously hard to remove from couch. The only way to really address this problem is to selectively poison the couch with roundup. This is a very painstaking process, but the only effective way to do it.

      To do this you take a plastic plate and cut to the centre of the plate, you then pull the blade of the grass you want to poison through the plate, and then paint on some roundup directly to the leaf. It is important to paint it with a brush and not spray it on, as run off from spraying will poison the surrounding grass.
