Concrete back yard
I am hoping to move to South Shields soon, but the flat has a concrete back yard. I need advice on how to make/seed/look after some sort of small raised bed to grow grass for my 2 dogs to use. I am also not sure if I need another raised bed to grow flowers or if containers/troughs/tubs will be better for flowers.
I have never really gardened before (just sweet peas for the last couple of years in a raised bed), and have no one to ask.Any advice given will need to be really, really basic.
