Weed ID - new top soil full of something!
Hi, I hope someone can help, we've just had 3 tonnes of topsoil delivered and after just over a week it is full of this weed/plant which we've never had before. It seems to be putting down deep roots pretty quickly. I can't find anything online to identify it. Can anyone help? I would like to know what i'm dealing with! Coin is a 5p.
