Pollination: Apple trees must be cross-pollinated by another apple or crabapple variety planted nearby with a similar bloom-time. Go here fora chart on which varieties to plant as pollinators.

Pruning: Apple trees are tolerant of different pruning methods. During the first 2 years after planting the tree should be trained to it's desired shape. The best time for pruning is in the Winter when the tree is dormant. If the tree is grown as espalier then the best time for pruning is during the growing season to train the branches.

A fascinating thing about the apple tree is its incredibly large genome. According to Wikipedia a Golden Delicious apple tree has about 57,000 genes! Compare that to the human geno

me of about 30,000 genes. This is also the highest number of any plant genome to date. It kind of makes you re-think the phrase "the apple doesn't fall far from the tree." Yes, the apple may not fall far from the tree-but you can bet your bottom dollar that its offspring will be vastly different! This is such a wonderful way for this plant to ensure its survival against pests and diseases. (Did you see that extensive list up there of how many it is susceptible to?)
There is so much to be said on this remarkable plant! It has

played an important role in history and mythology. Its biology is amazing. Have you ever cut an apple in half crossways to see its 5-pointed star?

It's amazing. It is beauty, and art, and symmetry in nature at its finest. If you have not watched the documentary The Botany of Desire I encourage you to do so. It is available to watch online through Netflix. (It is also a book, which I have surprisingly not read yet.) I gives a fascinating history of the apple and how it came to be what we know it as today. You will neverlook at an apple the same way again!
