You obviously meant to post something???

Oops planted living roof on top of dustbin store last year. Now looking very bedraggled with a lot of moss and all but sedum type plants have died. Also seems very wet despite having drainage holes at corners

Did the living roof have a substrate underneath it the 'mat' ?  We are about to instal one and I trust the company that recommends we have a few cms of inorganic, soil less (looks like a dried bark) substrate layer so that the roots can spread.  It is inorganic because you don't want to encourage any and every seed to colonise it.
