In a grafting workshop I took at the University of Guelph, held by Professor Henry Kock,
Interpretive Horticulturist, he indicated the key was sealing moisture into the scion while the
He has used Wilson pruning paint for hundreds of thousands of grafts of various trees and shrubs.
The advantage of the pruning paint is that the buds will grow through it, when they are ready too
and the pruning paint will not move around much (get under the rubber).
You paint over the grafting rubber, and the entire scion. This seals moisture in. In a year or
two after the graft is made, you will no longer see any evidence of the pruning paint.
He does NOT recommend using pruning paint for pruning cuts.
I have used his technique to great success. I was given an can of old grafting wax recently and
this season will try using it to seal the union and scion. Not sure if the heat of the warm wax
will injure the buds or not.
