I am very new here and to bonsai. I will be visiting the UK next summer. Has anyone been through this garden and should I make a special trip to walk the gardens? I do enjoy his videos and his approach.
Wisley is a nice large ornamental garden - have a look at https://www.rhs.org.uk/gardens/wisley/
Not that easy to get to without a car.
The 'bonsai walk' trees are what you see in the videos you link to - you won't find anything more.
