Low-Maintenance Country-Cottage Garden

Homeowner Emma works as a cabin crew member on long-distance flights. She bought her terraced house five years ago and has spent a lot of time and money renovating the inside, but up until now she's ignored the space out back. She wants to convert the dull, square, concrete patio into a beautiful, country-cottage-style idyll, but the design will have to be low maintenance because Emma's job prevents her from taking on anything that needs constant attention. And that's not going to be easy.
