The pedicel at the end of the shoot (red arrow) indicates that this shoot held a cluster of nuts last summer. When a branch is located within the lower portion of the canopy, the combination of partial shade and nut production slows shoot growth dramatically. With limited sunlight, the shoot invests all available energy resources into nut development rather that shoot extension growth.
Ultimately, short shoots make poor scions because the buds on the stem are too close together and the diameter of the stem is less than that of a pencil.
If you plan to graft a large number of trees, it pays to plan ahead. Develop your own scionwood trees this March and harvest high quality scions the following year. Once you finish grafting your orchard, scionwood trees can be left to grow normally and eventually return to become productive nut trees.
