Replanting Crops is a minimalistic mod which automatically replants crops harvested with seeds from drops. By default a hoe must be held for the replanting to occur, but this can be toggled in the config. By holding the sneak button, you can prevent the replanting as well.

Version 4.0 adds support for modded crops that extend the CropBlock.

Environment: Server

All available config options:

mustHoldHoeForReplanting default true
If enabled, players must hold a hoe in their hand to automatically replant the crop.

Works for wheat, carrots, potatoes, beetroots, netherwart, cocoa beans and various modded crops.

Harvest as many crops at the same time as you want. The drops will be used to replant the crop below.

By holding the sneak button, crops won't be replanted. Quite useful when clearing out a farm!
