I'm guessing these are ferns right? I've recently moved into a flat where the back garden has been left to ruin. The problem is I have a 5 year-old and we'd really like to get the garden to a usable condition (someone in their infinite wisdom put down stone chips which now has grass/weeds growing through it everywhere!). We'd like to have a grassy area as well as a nice border but at the moment it's a complete mess. Where to start? Well I have to get rid of these ferns anyway, and the only solutions I have found so far are to either dig them out (not with my knees...) or to use an XL strength weedkiller. Any suggestions?
