We have a garden full of weeds + a trampoline that we want to keep. I did want to put grass down, but that isn't practical because of the trampoline - that takes up a big chunk of our small garden. On youtube, I've seen videos showing people put down cardboard to suffocate the weeds + add woodchip on top. This would be ideal for us - giving a soft safe surface for the kids. Any thoughts about this? A good idea to do? One video said that doing this gets tons of slugs! Which, I'm not worried about - but the wife is!!
