Hello, We have a bedding area in our garden for our plants and one of the them grew a bit too wildly and continued on to our lawn, I should have cut it back but I allowed it to continue, I did cut it back a few weeks ago and the grass that it covered was brown in colour, It was only a small area at first but it seems to be spreading and it looks awful, Any advice on how to sort it out would be appreciated, Regards Cumnor.
