• I have some weeds growing out of the brickwork at the bottom of the house, various varieties.

    I want to use the strongest possible, yet cat and environment friendly, product to kill them dead.

    What should I buy?

  • Roundup is usually pretty effective.

    Opinions vary on how environmentally friendly it is, but use it sparingly and I doubt you'll be up there with clearing the Amazon rain forest in the league of crimes against nature.
