GROWING APPLE TREES
Some of the apple varieties with the most disease resistance are:
Liberty, Spartan, Priscilla, WineCrisp, Enterprise and Sundance. Priscilla has a slight licorice flavor and individuals that don't care for licorice don't care for this variety generally. The inside cover of ID-21 provides descriptions of these varieties. http://www2.ca.uky.edu/agc/pubs/id/id21/id21.pdf GoldRush and Pixie Crunch don't have all the disease resistance of the previously mentioned varieties but have outstanding flavor. The nursery source list is helpful in locating these varieties. http://www.uky.edu/hort/sites/www.uky.edu.hort/files/documents/HortFact3002_2015.pdf These varieties have no insect resistance so spraying is still necessary!
