Fruit growing on trees

I believe that by adding fruit trees to the game, not only makes more logical sense, but also gives an upgrade to the farming category of the game.

Instead of destroying trees and waiting for them to drop apples, there would already be naturally generated apple trees, you can tell the difference by noticing the leaves of the tree.

But fruit trees would have 4 growth stages before fully developing ripe fruit. For easier comprehension of the growth mechanic, let's use the apple tree as an example.

Growth Stage 1: Flowers start to form on the leaves, showing signs of pollination and the beginning of fruit development. (Ex: Flowers form on the apple tree's leaves)

Growth Stage 2: Tiny buds replace the flowers, being the first appearance of the fruit itself. (Ex: Small green apple buds appear on the leaves, replacing the flowers)

Growth Stage 3: The buds get bigger in size, and start showing color. (Ex: The small green apple buds grow bigger, and start showing red color)

Growth Stage 4: The medium-sized buds go even bigger, turning into the fruit's normal size, and turns to a full ripe color, ready to pick and harvest. (Ex: The green-reddish apple buds turn to full grown size, and fully red)

Players can grow their own Fruit Trees by obtaining the fruit off of a Fruit Tree they want and plant it into the ground, forming the tree's sapling. The Fruit Tree doesn't start producing fruit until it's grown.
