    In a podcast that John Kempf did, “Nutrition at critical points of influence”, he recommended applying a foliar spay before bud initiation. Based on sap analysis, it should contain adequate calcium, manganese, boron, zinc, copper and adding urea to provide freezing resistance. I recommend you listen to that podcast.
