Apple Generation Mod 1.4.7 makes apple blocks spawn underneath oak leaves in forests. The apple (block) will drop an apple seed if it’s still in the first and second stage. Otherwise, it will drop an apple (item) when broken on the third stage.
The apple (item) can be crafted into two apple seeds which can be planted underneath oak leaves.
The growth rate of the apples (block) is the somewhat fast (20% chance of advancing a stage every tick, you can change it through the configuration file).
With all said, it also disables the random chance of spawning an apple when destroying oak leaves.
From left to right: first stage, third stage, and second stage.
