During the last week of June and the first couple of weeks of July, I try to visit every successful graft I made this year. Pictured at right is a 3-flap graft made with a Kanza scion. The scion has made good growth but the rootstock below the graft has also sprouted several vigorously growing shoots. During this time of year, I like to prune off all rootstock sprouts and trim the scion down to a single shoot.
Earlier this Spring, the new shoot that sprouted from the scion terminated in a pistillate flower cluster (photo above left). The development of a flower cluster temporarily slowed the grow of the shoot but the terminal vegetative bud adjacent to the flower cluster eventually broke and started to grow. To promote the growth of that vegetative shoot, I pruned off the flower cluster (photo above right).
In trimming the scion down to a single shoot, I made two additional cuts. The first was to remove a shoot developing from the secondary bud just below the main new shoot. And the second was to remove the stub above the new shot. By making an angled cut, I will encourage the rapid healing over of the cut at the top of the scion.
