Growing your own food is not as easy as it looks. While it sounds like a great idea, the reality of tending your crops and fighting off weeds is too much for many.

But if you want some tips, then look no further. More than 100 food-growing community gardens will throw open their gates to the public.

The Big Dig Day, taking place on September 15 from 10am-4pm, will showcase mini-orchards, salad-filled parks and city forests across Brighton and Hove, with the aim to get thousands of people growing food together.

Jo Glazebrook, Big Dig co-ordinator, said: “The Big Dig Open Day is a celebration of growing in our city.

“There are so many active community growing projects in Brighton and Hove, mostly run by enthusiastic volunteers inspired to cultivate spaces in their community where people can learn and grow food together.”

Each space open to the public on the day will host a range of activities, such as making seed bombs in Preston Park and a picnic at The Orchard, Stanmer Village.

Ms Glazebrook said that London Road Station Partnership Garden, for example, has been transformed from a disused space into a community area with raised beds and fruit trees by a group of neighbours.

The idea behind the day is to display projects to the public. Nick Hurd, Minister for Civil Society, said: “The Social Action Fund is designed to help bring people together through innovative projects that can make a real difference in local communities. The Big Dig is doing just that – enabling community groups to transform unused spaces for everyone to share and enjoy.”

Brighton and Hove Food Partnership has linked up with Healthwalks, which will be leading a two-mile walking tour, meeting at 2pm in Stanmer Park, with the Bike Train Trail leading cyclists along the route, meeting at The Level at noon.

The event is co-ordinated by Sustain: The alliance for better food and farming, which advocates policies to enhance the welfare of people and animals and to improve the environment.
