In vanilla FD, Rich Soils will not bone meal any blocks that are tagged with #farmersdelight:unaffected_by_rich_soil here) to avoid unintentional behavior, like easy infinite crop farms with wild crop and the like. Resurgent Soil should do this check as well.

Also, the fungus colonies added in this mod never ticks because they share BlockProperties with their vanilla fungus counterparts, which do not have the .randomTicks() property. I think you should add that it would be cool.

wait, Resurgent Soil can make many plants spread, like crops, wild crops, flowers, grass, sapling...is it a bug or desigh?
