Enchanted Soil

Enchanted Soil is a block added by Botania. When a Mana generating flower is placed on it, it will work twice as fast. It is created by right-clicking an Overgrowth Seed on a Grass Block.

Once placed, the Enchanted Soil cannot be moved; attempting to harvest it even with Silk Touch causes it to drop as a Dirt block.

Legacy version
In Enchanted Soil would prevent passive Mana generating flowers from decaying.
