<p>This month we interview John Hanby, an expert in bonsai - the art of growing ornamental, artificially dwarfed varieties of trees and shrubs in pots. His book The Practical Art of Bonsai is published this month.</p>

This series will feature famous and not-so famous South Yorkshire people who are making a difference in Sheffield and beyond. We want to shine a spotlight on those whose efforts make this part of the world the best place to live and work in.
