These 'Kanzan' trees don't look top grafted, but I can't tell if they've been grafted at ground level. They're a row of street trees, on one block and then around the corner, all about the same size, so surely either all grafted or all not. But some appear to fan out at the base as if the trunk has sent down the roots, as the one in the first row, and others seem to have an uneven join to the roots at ground level, like the one in the second row. Is it possible to tell if they're grafted? and around the corner While I'm at it, what about this 'Shirotae'? Same question.
