đŋ Grass Block
Grass Block reacts to bone meal by growing grass and flowers on and near it. Internally it resolves a vanilla placed feature â a set of placement rules for what vegetation to spawn and where.
Exampleâ
blocks:
default:grass_block:
behavior:
type: grass_block
feature: minecraft:grass_bonemeal # the placed feature to run when bonemealed (required)

warning
- The block must have the tags
minecraft:dirtandminecraft:supports_vegetation, or grass and flowers spawned on it won't survive.
