The Apple Tree is a type of fruit tree. You can grow an Apple Tree by planting an Apple Sapling, which will take 28 days to grow. The tree will produce one Apple each day throughout the Fall season. Each year the tree grows it will produce higher quality produce, up to iridium. However if items are placed around the tree, it will hinder the growth of the tree and it not produce higher quality items.
If the tree is struck by lightning, it will produce Coal instead of fruit for a few days. Fruit trees may also be ground in the Greenhouse.
