Stage	BBCH	Notes
Planting and establishment	0	Grafted or budded onto rootstock rather than grown from seed (RHS; NC State Extension). Space 12-24ft apart, in a deep, fertile, sunny, sheltered spot (NC State Extension).
Vegetative growth	3	Grows on for several years before reaching fruiting maturity; full maturity takes 20-50 years (RHS), though grafted trees fruit much sooner.
Blossom and pollination	6	White blossom in mid-spring. Most varieties are self-sterile -- plant two or more varieties together as reciprocal pollinators for a good crop (RHS; NC State Extension).
Harvest	8	Fruit is harvested summer through fall depending on cultivar (NC State Extension).
