Hi everyone. New here as I have bought a new house in the last year and am looking to improve the garden. Firstly though I need help with a weed that is persistently growing in my driveway which is gravel. I have tried a weed killer on it which didnt work and already this summer I have pulled up the weeds 3 times and they just keep growing back. Theyre quite brittle so it's not always possible to get the roots. It looks sort of like Samphire. I need advice on how to eradicate it completely if possible.
