A Kent Council is offering a £500 reward to help track down "wanton" vandals who trashed a park's bedding scheme.
Gardeners discovered thousands of plants deliberately uprooted when they turned up for work at Folkestone’s Kingsnorth Gardens on the Kent coast.
Between 65 and 70 per cent of the 4,938 plants in the affected beds were ripped up and the rest trampled on.
Shepway District Council parks officer Laura Pinkham said gardeners worked hard to replant as quickly as possible, but there was no guarantee that the plants would survive.
"Our gardeners, who take such pride in Kingsnorth Gardens, are devastated," she said.
"We bought the plants for £1,471 and it took four men five hours to replant at a cost to the council of £400.
"We have reported this damage to the police and anyone with any information should contact them."
Council leader David Monk, said as well as a monetary cost, the plants were valued by residents and visitors.
"A lot of people love these gardens and have been saddened by the news of such wanton vandalism. The culprits need their heads banging together."
A £500 reward is being offered for any information leading to an arrest and charge.
