Seems to be coming from the roots, i.e. you didn't cut the turf deep enough. I would put plastic bags over the rose / geraniums, and spray the grass with glyphosate.

Thanks @GardenerSuze, I only posted that because I remember being despondent about ever getting the grass and weeds to a manageable level too. But as everyone has said it's all about consistency and time.
Is that right about the grass clippings ending up in the border that they can take root? I have heard conflicting views. I use a strimmer once a week and hard to keep the clippings out of the border. I guess more mulch and landscape fabric would help with that too.
By the way, If i do put the fabric down and bark chippings on top, I do need to remove the grass first right? Wishful thinking but the fabric and chippings won't be enough to kill what is there will it.
I think you're right re the grass not been cut out deeply enough @Loxley. That's exactly what that looks like - new growth from the grass itself. You need to remove a good 3 inches of turf - the soil itself, not including the actual grass.

@Loxley and @Fairygirl yes, seems right, I could scrape a way wood chippings and dig out more deeply (assuming laying the landscape fabric won't kill it?)
Also, would a Geranium Rozanna be hindered by landscape fabric - I gather they run/spread through a border so I wonder how it could do that with fabric in place.
If you have the fabric, plants will be less likely to spread easily, except by seed. Depends on the thickness though. If it's thick enough and with the bark on top as well, the grass will struggle more to grow too.
