Each week award-winning gardener Diarmuid Gavin comes to the aid of families looking to revamp their backyards. However, it’s up to the families to do all the work if they want to create the garden of their dreams. Diarmuid’s design, creative flare and advice are all free of charge. However, each participant sets the brief, puts forward all the finance and then has to don the wellies as they set about creating the garden Diarmuid has designed for them.
