I've always lived in flats until recently, but have been in a house for a few years. There's a yard, which is paved but a few plants sprouted which I rather liked, and bees & butterflies were attracted, which was lovely. But it's got out of hand - and I just don't know where to start. I don't want to kill any insects, or plants really, but I suppose I'll have to pull some up. I've also no clue which are weeds and which aren't. I'm wondering whether I should pay a gardener to sort it out, leave it be, or move house! Any advice would be very gratefully received.
