Chris Bonnett had staff at his nursery in Essex speak to plants in different accents each day as an experiment.
Different groups of plants were placed in separate areas, with DVDs and CDs of regional soaps and popstars played to each. Staff ensured the accents were never mixed up.
The 'Geordie' plants, which listened to Geordie Shore, Cheryl Cole and Ant and Dec, grew almost 10% more than those in other groups.
"We kept all other variables as constant as possible. So the plants all had the same amount of sunlight, water and nutrients," Bonnett told The Mirror
"By the end of the summer it was clear that the accents had a huge effect. There was, more or less, average growth across the Australian, Liverpudlian, Yorkshire and American groups.
"The Geordie and Welsh groups visibly thrived and displayed enhanced growth while the Scottish, Chelsea and Mancunian plants were stunted."
