My block paved driveway is full of liverwort growing between the bricks. How can I kill it for good? I have tried Weedol, Pathclear, sodium chlorate but nothing seems to get rid of this stuff.

Weedol, Pathclear and sodium chlorate are weedkillers that only kill weeds – having no effect on ‘lower plants’ like lichens, moss and liverworts.

There are a number of path cleaning products available from DIY stores and garden centres that will kill them, but check the label first to ensure it mentions this fact.

Bayer Advanced MossKiller, which contains natural fatty acids, is effective against lower plants. I used it earlier this year with good results. Be careful when applying it as it will also damage or kill plants that it comes into contact with, so ensure the spray doesn’t drift onto wanted plants or the lawn.

On another matter, sodium chlorate has been taken off the market and you have until May 10, 2010 to use up any stocks you have. After this date it will be illegal to use it

Our Tarmac drive is green where pine needles etc. have come down over the years and algae has started to grow on the Tarmac. What do you suggest?

There are a range of products suitable for removing stains and moss from Tarmac - just check your local garden centre or DIY store. Alternatively, try washing with a pressure washer.
