My back garden has become infested with a weed called 'Bittercress' which is very invasive if allowed to seed. It can grow from a seed to maturity, flower and set hundreds of seeds in one month. All this happened while I was feeling under the weather, I have sought professional advice and was told it can be a real problem. The advice was/is to remove all the visible growth from the surface then hoe the area before covering with a 3" mulch of shredded newspaper and leave it until next spring. The bittercress will try to grow but it will fail and get tangled with the paper shreds and die before it can seed, then after the winter I have to light a small fire in the center of the patch and draw the paper shreds onto the fire with a rake a small amount at a time. This will take the weeds with and it will all get burnt away, for this procedure I have filled and used half a dozen dustbin bags full of shredded newspapers. Much of it cut into boot-laces with scissors because my electric shredder is a cross cut one and the pieces would be too small. I only have the runner beans and beetroot in the veg patch so it should be an easy summer for me from now on.
