Green-fingered volunteers set about task after learning that the St Leonard’s Community Hospital was to lose its garden for development.
The Ferndown Dementia Friendly Town steering group, chaired by Harry Worth, secured the plot from the town council.
A fundraising effort was launched and it allowed raised beds to be installed, along with paths laid and wood chippings added. A dilapidated shed has also been replaced with a summer house.
As well as the town council and the Douch Family Funeral Directors branch AE Joliffe and Son, the Ferndown RBL Club, Dudsbury Golf Club, Colten Care’s Fernhill Dementia Home and Rotary Club of Parley have all helped raise the amount required.
The Mayor of Ferndown, Cllr Mrs Cathy Lugg, will open the new facility on October 7.
Emma Regan, from Douch Family Funeral Directors, said: “This is an important community project which we are proud to be involved with.
“Many of our staff have had ‘dementia friendly’ training and understand how important things like this can be for those with dementia.
“The RBL Club, Dudsbury Golf Club and Rotary Club of Parley have all come together with other volunteers to make it a reality.
“The allotment will be a fine addition to the town’s facilities and as well as helping those living with dementia will hopefully produce some lovely vegetables.
“There will be a grand opening with dignitaries and volunteers attending.
“The steering committee is looking forward to having a number of different types gardening clubs set up at the allotment.
“These will include those for people with dementia, befriending groups and others in the community.”
