Hi guys I am new to the forum and also new to gardening. Looks like a great place to learn and connect. We moved into our house about 18 months ago and we are trying to get our heads around gardening :D We've noticed that the following (see attached pic) has cropped up on a particular part of the lawn following the recent hot weather (based in London). I assume it's a weed. So I have a couple of questions: 1) Do you have any suggestions as to what it might be? 2) How best to tackle the area to remove the weed with affecting the rest of the lawn? Thank you in advance!
