Grass is a Resource Node found throughout the most part of the Backyard. It can be harvested with any axe and is most notable for giving Grass Planks and large amounts of Plant Fibers. It has three grass variants, a single strand, double strand, and triple strand that gives varying amounts of grass planks when chopped. It will continue to regrow unless the player builds within its proximity or chops its stem, in which it will stop growing.
They can be grown in a Garden Patch using Grass Seeds.
Harvesting enough will unlock the Grass Master mutation.
