I'm beginning to think there's something to this 'highworking' phenomenon.
I grafted some kaki persimmons 2 and 1 yr ago - all froze out this past
winter, except for 3 varieties(Great Wall, Maekawa Jiro, Saijo) that I had
topworked(I had leftover scionwood) onto some large D.virginiana seedlings
last year - about 5 ft above ground. These look great.
USDA Zone 6
