Pollination

Pollination occurs when pollen is transferred from one blossom to another.  Apple trees require pollination in order to produce apples.  Cross - pollination is when pollen from another variety of apple tree is needed for the apple tree to produce fruit.  If a tree requires cross - pollination it is called self - unfruitful or self - sterile.  If it does not need cross - pollination, it is called self - fruitful, self - fertile or self - pollination.  Apple trees can be either self - fruitful or self - unfruitful. 

Most apple trees require cross - pollination from another variety of apple tree to set fruit.  Red delicious apple trees require a cross  - pollinating cultiver to bear fruit so if you want your Red delicious apple tree to set fruit you can choose from many compatible cultivars.  Pair two of more of the following mid to late season apple trees, Jonathan, Red delicious, Golden delicious, Granny Smith, Fuji, York, Gold Rush or Rome.

 Hopefully this will be helpful to all of our Apple lovers.
