Dealing with weeds

Someone told me that to kill weeds they should be watered when the weather is really hot - is this correct?

    Hi Heidi - on the contrary, most weeds would be grateful of the drink and would only grow stronger!

    However, you're not alone in believing water can kill plants in hot sunshine. The received wisdom goes that water will scorch the leaves; but a recent study by Hungarian scientists proved this to be wrong.

    Ken Thompson wrote a good article about their work in the Telegraph in 2012.

    That said, boiling water poured on weeds (for example in the cracks of pavings) will kill them. So next time you have rice or pasta, or boil a kettle, give it a try with the scalding water. But do not pour it on your garden beds as this can damage the quality of the soil (the organisms within it) and kill the plants it touches.

    When the weather is sunny, even better if windy too, hoe off the weeds and watch them wither and die! If you have tap rooted weeds like docs and dandelions, and they are well established, then you'll need to fork these out first before you hoe-off the rest.
