* 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.
