Fans of his main rival and colleague, Alan Titchmarsh, argue Monty will always trail in popularity.
Yet, Monty in his own right has built up something of a cult following.
Known for his often self-deprecating yet incessant and hardworking nature, Monty often makes himself the brunt of the joke.
This was especially true when in 2018 he revealed to The Guardian his most embarrassing moment.

It came while dealing with a client whose garden he had helped with beautifying.
Monty explained that the ordeal still “makes my toes curl”.
He said: “A banker whose garden I had helped with rang to arrange a visit.
“As the conversation finished, I meant to give my love to his wife but it came out as a rather high-pitched: ‘Love you!'”

The gardener has, in the past, also been heavily critical of his own actions and decisions throughout his life.
In a separate 2009 interview with the publication, he revealed how his “yes man” attitude had niggled away negatively at his life over the years.
Lingering on how his work impacted upon his wife Sarah and his children, he said: “Ask Sarah what the worst thing is about living with me and she would probably say that I always put work above everything else, to the detriment of my children, my wife, my health, my life.
“And what I am really bad at is saying no.”

One of these came at the beginning of the Nineties after he and his family neared bankruptcy.
It came after the couple’s jewellery business fell apart and they moved to their current Herefordshire home.
