Late March, 2004 I tried, without success to whip graft several hazelnut scions onto 7 year old hazelnut trees. I followed the same technics that have been very successful with apple, pear and stone fruit grafts.
Can hazelnut be whip grafted with good success and if so what is the best time of the year to graft?
Hazelnuts are very difficult to whip graft. If there is a good time to graft it would be in the spring. The success rate is low. The preferred method of propagation for hazelnuts is layering in special beds.

In my "hey days" of grafting I was determined to graft over some native hazelnut trees to Commercial "Filberts." The wood was good, the eyes (mine) were good, the grafts were too; but not one "took." I'd tried cleft grafting, not whip & tongue, but as the cleft graft had worked on everything around my homestead, I figured "Hazel nuts" were simply a different Animal!
My reseach indicates that the lack of heat to heal the graft wound inhibits whip grafting success in natural conditions. Don Blazer, from Mt. Vernon, Wa. tells me that nut trees need a constant minimum of approx. 80 degrees F. for the graft wound to heal. Nut tree grafting can be successful using artificial heating, the area of the new graft is placed in a heat tube until the wound heals over. I'm not sure how long this takes or the ideal time of the year to use this technique.
