WIGHT in Bloom is in danger of dying after organisers failed to find new sponsorship.
Competition organiser, Peggy Jarman, from Seaview, said: "In the past we have had support from MiracleGro, then from Wightlink and more recently from the IW Council, but this year they have all declined to help fund the project.
"We only need £3,000 to run the competition and I do hope that all those who want to see the Island at its best and as a flourishing tourist destination will think of how they can help out."
Sponsorship enables voluntary groups to buy plants for their communities and for organisers to stage an awards evening.
Mayor of Ryde Cllr Wayne Whittle, who last year accepted first prize on behalf of the town, said: "Wight in Bloom has in past years been a real crowd puller for the Island, encouraging our towns and villages to put on their Sunday best for our visitors and brightening up the whole Island.
"We all benefit from a more colourful environment and a boost to the tourist trade."
The Tory IW Council spokesman for tourism said: "The end of this competition will be one more nail in the coffin of the Island as a great tourist destination."
