I am writing a book on pruning.
I can’t get it finished just now as I’m busy actually making topiary, but more details to follow sometime…
You can get a head start by watching a video about topiary technique, plants to use, best tools and the sort of shapes you can design by renting The Modern Topiarist via Garden Masterclass…
If there is a pruning topic you wish to read about in the book, let me know via the contact page.
