The hedge was causing the couple stress (file pic)
Charles Baillie, who has lived at the property for 44 years, said: "The sale value of our property will be considerably reduced should we decide to sell the property in the future.
"Both my wife and I are over 70 and have continued health issues.
This decision by Stirling Council has caused both my wife and I considerable stress and will cause physical hardship attempting to maintain our side of this hedge even at its present height."
In a letter Stuart Jenkins said: "I can confirm that we will carry out annual maintenance on the hedge to keep it within the current range."
The letter added: "It was never our intention to be difficult about the hedge height, we just really value the privacy the hedge gave us in our back garden.
A spokesperson from Stirling Council said: "The current hedge height is not considered to have a negative impact on the light levels to garden and house nor the occupant's enjoyment of their property."
Anyone considering applying for a high hedge notice must have tried to settle the issue with their neighbour before making an application.
In Scotland a high hedge is considered to be more than two metres tall from ground level.
