When I was out putting in an air layer on an impulse I decided to try a summer graft. Here is the graft done late June with red mulberry onto M. alba rootstock. The rootstock had two trunks and I grafted one leaving the other in case it was a dud. The graft was sluggish and budded out on the lowest bud until I finally cut off the other trunk and now has growth on the upper bud. I’m hoping it continues to grow.
