The Valent/Cornell University Young Apple Thinning Gauge

The gauge is placed one foot up the trunk of young apple trees to determine how many apples the tree should have to prevent biennial bearing. On this Honeycrisp (H) tree and other varieties prone to biennial bearing, there should be app. 32 apples. For Gala (G) and other varieties that can carry a heavier crop load there should be no more than app. 48 apples.
