Your own garden
If horticulturally suitable, and you have one, your own garden is probably the most convenient for growing food – and that includes your front garden, as Back to Front is proving. And if it isn’t suitable you can always use raised beds, containers, pots etc on patios, yards, walls, balconies or even roofs – as outlined here

The Back to Front Manual is packed full of fantastic ideas and advice http://www.backtofront.org.uk/?page_id=17
And the Back to Front Community Guidelines booklet is even easier to follow than the manual http://www.backtofront.org.uk/wp-content/uploads/2014/02/Back-to-Front-Manual.pdf
If, however, your own place is not suitable, you might consider growing in a garden or space you share with neighbours, or coming to an arrangement with a garden-owning friend. Other options include school grounds, hospitals, business premises etc. How about starting up an employee’s allotment at work?

If you do share, remember that it’s vital that both parties agree from the outset what to expect (often it turns out too late that one or other had unrealistic expectations) and if necessary that any agreement (for example, who gets how much produce, who’s responsible for watering etc) is made in writing.
