I have been fighting with couch grass... and it has been winning. So I looked around the garden to get some non fighting ideas and I notice that it doesn't grow under any of my daisy bushes. Even though there is plenty of light under these bushes. I mean it will grow merrily through geraniums that are denser than my daisy bushes. So I am going to plant all my garden bed boarders with all sorts of daisy bushes, low growing daisy plants and see what happens. In the meantime, could this community seek out any daisy bushes in the garden and if you have couch grass near by see if it will venture under the daisy bushes or not please
