Wasteland garden.....please help
We desperately need to sort our garden as we have 3 young children desperate to play out there, our garden is 18m by 12m and we want to section it off ie, patio or decking, play bark and kids toys at bottom and a vegetable patch beds flower beds......anyhow the garden has never been tended to and full of massive bumps and dips of compacted grass and stinging nettles.
What is the best way to level it out and kill the weeds and grass so we can re turf etc? I know tonnes of people probably asked asked this before but it's so daunting When gardening is not our hobby, have attached a pic it has so much potential. We have been told to rotavate it, but won't doing that mean that the weeds just grow back? Thanks in advance.
