Cut Grass is a renewable resource item harvested from Grass Tufts found naturally in the world. It can be used on numerous starter recipes and in even more advanced items when refined into Rope.
Because Cut Grass is needed to craft campfires and torches, it is a valuable early-game resource to collect. A player who does not collect cut grass on their first day will have no means for making a fire at night.
In Winter, Cut Grass becomes a non-renewable resource, as harvested Grass Tufts will not regrow until Winter ends.
Reign of Giants
In Reign of Giants, Cut Grass is used for new crafting recipes as well. It now drops from all Tumbleweeds, making it renewable even if the player burns all the spawned Grass Tufts.
Cut Grass can also be gained from crops on a Farm that are destroyed by the heat during summer.
