To our local garden centre yesterday evening to get something really toxic to put on the weeds that keep growing through the cracks on the terrace and the gravel on the drive. Only to discover that they've gone all environmental and don't sell toxic stuff any longer. The alternative is a thing that warms up the little weedies with a gas flame. The instructions explain how heating to between 75 and 90 degrees does something to proteins, and there are some before and after pictures with a dandelion looking a bit off colour. Back home to try it out, and *it's a flamethrower*!! It makes a tremendous roar, and it sets fire not only to weeds (I totally don't see how you can just use it to warm them up a little) but also to garden furniture and my espadrilles. Complete win!
