You can kill individual weeds on the patio by pouring on hot vinegar. This treatment is for paths and patios and not your lawns or borders. The white vinegar treatment might take a short while but the patio should remain clear fora good few months.
Let me know how you get on.

Dedicated to building TBO Malvern but I still like to find time to play golf, usually on a Friday afternoon.Decorating and gardening is best left to the lovely Mrs Cook!
