Volunteers are being urged to get busy in three Hackney community gardens this Saturday in the Big Dig, a nationwide project to get people growing food together.

Dalston Eastern Curve garden, Linzell Estate forest garden and Homerton Hospital’s Picu Bevan ward garden are joining 70 food-growing projects across London which are all opening to get a head start for the growing season.

Volunteers can arrive between 11am and 6pm at the Dalston Eastern Curve in Dalston Lane to help prepare the garden for spring.

Weeding and seed sowing, as well as socialising and table tennis, will be going on all day at the forest garden on the Linzell Estate, which is parallel to Marsh Hill in Lower Clapton.

Volunteers are also invited between 10am and 4pm to the Bevan psychiatric intensive care unit’s garden in Homerton Row to help out with planting.

The Big Dig Day in London is led by Capital Growth, a food growing network supported by City Hall.
