The entrance to the rose garden in Bushey became the subject to a fly-tip on July 25, after a torn apart mattress was dumped on the grounds.
This comes a month after Bushey Rose Garden attained their Green Heritage Site accreditation, for its historic features and standard of conservation, for the ninth year in a row.
The Bushey Rose Garden took to their Facebook page to ask followers if anyone knew anything about the rubbish that had been dumped.
They said: “Our beautiful garden had a very unwelcome visitor today. Who would do such a thing? If anyone knows anything about this please PM us or have a quiet word with Conor, our gardener.
“Maybe some restorative justice would help the perpetrator develop a love of the garden and stop them from any future fly tipping.”
The Bushey Rose Garden gardener, Conor Graham, said: “I was in the garden all day and had been working on the high street side of the garden, I only noticed the mattress in the afternoon around 4pm when I left.
“I alerted the friends of the garden who immediately shared it on social media groups to alert others and we had over 50 comments of peoples annoyance, as well as some lovely offers to remove it and warm sentiment towards the gardens importance in their lives.
“The mattress was clearly very dated and breaking down and was not fit for anyone but a professional to deal with.
“I had plenty of people come and tell me how horrified they were of this happening and as we don’t have any CCTV cameras that can view as far down as that we are sad that no one was able to see the perpetrators or pass on any further details to the police.
“We are looking into the cost effectiveness of having CCTV installed over the entrance to deter this from happening again.”
The fly-tipping was dealt with within 24 hours.
