Dunorlan Park won the top grade for the second year running, meanwhile Oakley School received a gold in the Schools in Bloom category. The final award given to Royal Tunbridge Wells was best in Kent across all categories.
Contract service manager Mel Henley said: "So many people from officers and councillors to Sodexo’s gardeners and street cleaning teams have worked with community groups and volunteers to ensure that our beautiful town looked its absolute best."
This year the local in Bloom group planted troughs to increase floral displays in the town centre and organised community projects including hedge laying, spring cleans and conservation activities. The group also runs competitions for residents.
Councillor Jane March, responsible for tourism, leisure and economic development, said: "These awards enhance the importance of borough as tourist destination and thanks are due to volunteers, staff and members."
Royal Tunbridge Wells in Bloom councillor Ronen Basu said: "This confirms what people tell me when they say they think the town looks very beautiful. It is a prestigious competition and we should be very proud of our achievements."
Funding for Royal Tunbridge Wells in Bloom comes from the borough council, Sodexo, Cory Environmental and Kent High Weald Partnership.
