Plum grafts on wild choke cherry

Plum grafts on wild choke cherry. Our grafts were all done in the first three weeks of May and many are showing signs of growth, so a successful union so far. The take rate seems to correlate with age of the root stock and competing vegetation on it more than shade, type of graft or plum cultivar. In the fall we’ll post a spreadsheet with some data, this is a multi year project to determine compatibility in cold hardy Prunus cultivars on the most prolific and hardy wild Prunus rootstock (Prunus virginiana) in our climate zone 3, southern Manitoba. #grafting #chokecherry
