Summary
Apples are pollinated by insects, with bees and flies transferring pollen from the flowers of one apple tree to those of another. But you don't need to plant a whole orchard to enjoy apples right off the tree. Two trees will reward any family with enough fruit to enjoy and share with friends. Apples require pollen from a different apple variety to grow fruit. If you only have room in your yard for one tree, there may be crab apples in your neighborhood to provide the pollen your tree needs.
