Chris Bavin is in the market town of Amersham in Buckinghamshire to meet a group of Bloomers who are determined to win gold for the fifth year in a row and unite Amersham. With only seven weeks until judging day, they have come up with an ambitious plan to impress the judges, but they will need help from an army of volunteers. Firstly, they are creating a brand new centenary garden at the entrance to Top Amersham. Next, they have organised a competition amongst 400 school children to design and plant four new raised beds in both parts of the town. Finally, in Old Amersham’s most important location – its stunning Memorial Gardens - the Bloomers are creating not one but three show-stopping displays to commemorate 100 years since the end of World War One. But a record-breaking heatwave threatens to scupper their chances of winning another gold award.
