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

Hi Ilse, welcome to permies!
I hear you about fighting couch grass... it took me years to clear a fairly small area, picking tiny bits of roots out of one shovelful at a time...
I have no daisies here except little tiny ones mixed in around the meadow... I had no idea what a daisy bush was... https://en.wikipedia.org/wiki/Olearia makes it seem likely that they're at least the same family as whatever mine are.
I'm keen to hear how this experiment goes, I would love another option than the combined mulched path/plastic/trench that I used now.
A latin name for this 'daisy bush' would be handy, or some other more specific identifier? For that matter, can you confirm that your 'couch grass' is 'Elymus repens'?
