Previous efforts have turned up a mattress, old Christmas trees and a road barrier, but community activists are now planning a root-and-branch clean up of Surbiton's Claremont Gardens.

The Surbiton Wildlife Group has secured a £1,500 grant from Mayor of London Boris Johnson to pick, prune, weed and fertilise the small park over two days next month.

Help chop down unruly foliage and clear the way for a roomier, cleaner park.

Organiser Tom Hooker said: "It's just an initial tidy up to do basic things, just to freshen the whole place up really, and make it look better. There might be a bit of planting, foxgloves and stuff like that."

Head along from 12pm to 6pm on Friday, July 17, for a preliminary litter-pick ahead of the big day on Saturday 18, which runs from 10am to 6pm. To sign up, or for more information, contact surbitonwildlife@hotmail.com or search Surbiton Wildlife Group on Facebook.
