A crew of ten has been methodically hard pruning the ginkos on the main street in front of our apartment complex. I am amazed at the skills and resources devoted in Tokyo to public trees.
In San Francisco, the city is content with a 20 minute training session and a couple of chain saws. In Tokyo, trained arborists climb the trees, use hand saws and prune the trees into perfect shapes.
Look how much more vigorous and vertical the ginkgos are. Much more of a tree tree in warm, humid summer climates.
