The hedge was last professionally re-laid in 1995
A group of residents from Henleaze plan to restore an ancient local hedge, which historians say could have been planted as early as the 1300s.
But they say Phoenix Hedge has become badly overgrown and needs to be professionally re-laid.
Local resident Sylvia Kelly says currently the hedge looks "awful" and is appealing for more volunteers to help restore it.
It could cost as much as £5000 to bring the hedge back to its former glory.
The Phoenix Hedge is so old that no-one knows who actually owns it, or the land that it grows on.
It was last re-laid 14 years ago and, in according to Sylvia, "should have been done [again] by now".
It runs between Phoenix Grove and Henleaze Park - hence its name - and straddles the Henleaze Junior School playing fields and Golden Hill Sports Ground.
Sylvia told BBC Radio Bristol's Steve Le Fevre that six different trees that make up the hedge and they help to date it.
"Each woody tree counts for a century and there are six woody trees," she said. "It is a scientific way of dating the hedge."
These are hawthorn, sloe, blackthorn, ash, elm and spindle - spindle "only occurs in hedges that are 400 years old", added Sylvia.
She says that nearby schools are taking an interest in her campaign and that they are thinking of using the restoration as part of their curriculum.
She, and other local hedge supporters, are planning a "hedge action day" later in the year.
