Volunteers have hit out at the vandals who have scrawled graffiti across the town.
Chatteris in Bloom Committee was horrified to discover graffiti sprawled over two of their displays last week.
Tags have also been sprayed on postboxes, walls and fences.
In Bloom vice-chairman Tina Prior said: “There are a lot of people who put in commitment, hard work and time and effort in putting these things together for the community.
“And it feels a real shame to scrawl on the banners. There is no specific art work.
“It is really disappointing that someone felt the need to do this.”
