Blonde Girl In The Garden With A Ladder And Apples

• Pollination
Apples are self-incompatible; they must cross-pollinate to develop fruit. During the flowering each season, apple growers usually provide pollinators to carry the pollen. Honeybees are most commonly used. Orchard mason bees are also used as supplemental pollinators in commercial orchards. Bumble bee queens are sometimes present in orchards, but not usually in enough quantity to be significant pollinators.
There are four to seven pollination groups in apples, depending on climate:
Group A – Early flowering, May 1 to 3 in England (Gravenstein, Red Astrachan)
