Update from post August 25, 2010
The 'Lee Valley Grafting Tool" was a dismal failure and I would not
recommend it. Of the thirty grafts attempted not one grew. Quite a
disappointment for I was excited when I purchased the tool erroneously
thinking that all grafting problems would be eliminated. In 2011 I
grafted another thirty scions (the old method)and have high hopes of
success. I have been poking around the grafts (which I shouldn't do but
cannot control myself) and see promising buds!
Looking forward to spring and the peony season.
