Managing Pruning and Fertilization of Honeycrisp to Balance Growth, Cropping etc
Mike Basedow, Tree Fruit Specialist
Eastern New York Commercial Horticulture
Bitter pit in Honeycrisp is affected by tree vigor which in turn is affected by both pruning and fertilization levels. Thus, to achieve a balance between vigor and fruit quality we must manage both pruning and fertilization in a coordinated manner. When deciding how severely to prune a Honeycrisp tree, we should consider flower bud number per tree and also leaf nutrient levels and the peel sap nutrient values, which we have been collecting statewide over the last 2 summers.
