In the spring, after a period of dormancy, the tree starts to show signs of life. The bud begins to swell. The flowers of the bud open up and bees pollinate the flower. Leaves start to grow on the trees.
In the winter the tree remains dormant. The apple trees prefer a cold winter.
In the autumn, the leaves fall off the tree and the tree becomes dormant.
The flowers which have been pollinated by the bees develop into apples during the summer. Apple trees like a warm summer with some rain.
