Residents are being urged to “put on their wellies” and join in a host of outdoor projects taking place across Camden, Haringey, Barnet and Westminster next month, as part of the annual Mitzvah Day.

Volunteers are invited to spend the day feeding animals on Kentish Town Farm, dusting down Karl Marx’s grave in a clean-up of Highgate Cemetery or brighten up their community’s outdoor spaces with tree and flower planting.

All part of the Jewish charity’s global annual day of social action on November 16, organisers at Mitzvah Day say going green plays an ever-growing part of its yearly event which sees hundreds of thousands of people of all faiths and backgrounds donate time to worthwhile causes.

Last year’s highlight saw a trip to Kentish Town City Farm where young volunteers helped feed animals and clean up their habitat.

Naomi Ackerman, its project manager at Mitzvah Day, said: “Situated in the middle of an urban area you would never think it was there, but when our group of 20 teenagers arrived on Mitzvah Day last year we saw local eight-year-old boys helping feed goats from their mini-wheelbarrows!

“We said a quick hello to all the animals, including giant chickens and a friendly pig, before weeding areas, shifting old wood and taking rusty nails out of planks so that they could be used to build a new shed. We were doing useful things for this farm which brings the local community together.”

Volunteers will be returning to the farm this year and a number of other projects are also looking for help.

Children from Rimon Primary School in Dunstan Road, Golders Green, will be bringing “spring cheer” to elderly members of Golders Green Synagogue with their own decorated plant pots, while the JW3 in Finchley Road will be inviting residents to help improve their community garden.

One group in Crouch End, which transformed a disused piece of land into a permaculture garden, orchard and wildlife meadow, has been championed by the charity for showing what is possible.

The Meadow Orchard Project was launched five years ago and has since developed into a group of almost 200 members, including 50 families.

Dave Cohen, of the group, said: “We began taking part in Mitzvah Day in 2010, and each year it has sent several volunteers to Meadow Orchard. It’s always amazing to see how the area has developed.

“Meadow Orchard is exactly the kind of project at which we should all be spending more time. A previously disused chunk of land, reclaimed and turned into the kind of place that can create a sustainable future for our children and the generations that follow.”
