I've added the functionality of this mod to Serene Seasons, so if you want even more seasonal features, go use that instead! It even has a few more features than this mod!
This mod adds the 4 seasons into Minecraft, and allows users to configure what crops are fertile during which season. If a planted crop isn't fertile during the current season, it'll break when it tries to grow.
For use in modpacks where the creator wants to restrict what plants players are able to grow during which season.
