Horsetail. Bad luck!
I got it in a house I bought last year, coming up in my lawn and drive. I used a total weedkiller on the drive - forget the name but it does what sodium chlorate did before it was banned - stop anything growing for 6 months. On the lawn I wore a rubber glove and wetted my fingers with glyphosate, shaking off any excess, and then bruising the horsetail. I had to dfo this every week for months as new shoots appeared. It seems to have gone.
My mum has been digging this out since 1956 when they moved in to their house. You can't get the roots out, they'll come through tarmac, and because of the waxy coating weedkillers just roll off. Good Luck.
It's older than the dinosaurs and it's as big a thug as you're likely to find unfortunately. If you type horsetail in to the search box you'll find loads of information on how to deal with it from previous threads. Good luck!
Dammit, thanks all! Kind of figured it was a nasty one, still now I know it's a toughy, let the systematic battle begihis. Was just hoping it had a big weakness! I may never eradicate but as long as Uighur can keep it at bay I'm happy.
one more question thoughdrive planted shrubs in the border, when they're fully established will this weed be shaded out or not??
No it won't. It has tremendously long roots so the only way is weedkiller. At the RHS garden I saw on TV, think it was Harlow Carr, maybe Hyde Hall, they used glyphosate.
