* Choose varieties which have overlapping bloom periods. For example, 'Gala' and 'Empire' have overlapping bloom periods, whereas 'Paula Red' and 'Fuji' do not overlap. 'Mutsu', 'Stayman', 'Jonagold', and 'Winesap' are varieties with sterile pollen, which makes them unsuitable as a pollen source. 'Golden Delicious' is a good pollinator for these mid-season varieties, but will not pollinate 'Jonagold' or 'Mutsu'. Although some apple varieties do not require a pollinizer, fruit size and fruit set will be greater if cross pollinated. It is recommended to plant at least 2 to 3 apple varieties with overlapping bloom periods for optimal fruit size and set. Varieties such as Arkansas Black or Winter Banana have extended bloom periods which make these varieties good choices as pollenizers. Flowering crab trees also can be used as a pollenizer as long as the bloom periods of the crab apple and apple variety overlap.
