'''Grass''' is a naturally occurring resource that is present in the [[Spring]], [[Summer]], and [[Fall]] seasons. At the start of the game, the player's farm has many unconfined fields of grass. Each day, it is likely that existing grass will expand and grow into adjacent unoccupied tiles. And occasionally, grass will spawn randomly on unoccupied tiles anywhere on the player's farm. Also, the player can choose to start a new patch using [[Grass Starter]], which will create a fully grown tile of grass where the player places it.

Blue Grass

Blue Grass

Blue Grass appears naturally on Meadowlands farms. A recipe for Blue Grass Starter can be purchased in Qi's Walnut Room for data-sort-value="40"> 40, which allows Blue Grass to be placed on other farm types.

Animals eating Blue Grass gain twice as much friendship as from eating normal Grass (16 instead of 8).[2] If successfully cut with a Scythe, Blue Grass will produce two pieces of hay, instead of the usual one.[1]

Animals eat half the amount of tufts of Blue Grass compared to normal Grass (Coop animals 1 instead of 2 tufts, Barn animals 2 instead of 4 tufts).[3]

Tips

  • Grass will only naturally spread to tillable soil tiles. It will not naturally spread on green, 'grassy' tiles.
  • Most paths, fences, closed gates, or pieces of furniture (such as chests or braziers) prevent the spread of grass through the tile it occupies.
  • It is possible to exploit this by sectioning off patches of grass in animal enclosures, preventing them from eating all the grass in the area. This allows the grass to regrow more quickly, stemming from the fenced-off source patch.
  • Placing a fence on any type of grass will prevent Animals from eating it.
  • Blue Grass does not spontaneously spawn on any Farm Maps except for the Meadowlands Farm.

Notes

  • Grass has a -1 Speed penalty, unless the player has read the Ol' Slitherlegs book, which reduces the penalty to -0.33. There is no speed penalty when riding a horse through grass.

Propagation

Each fully grown grass tile consists of 4 tufts of grass. Each day, every individual tile containing normal Grass will grow 1-3 tufts (randomly determined).[4] Additionally every tile containing normal or Blue Grass has a 65% chance of growing. If the tile containing grass has less than 4 tufts and succeeds a growth check, it will grow 0-2 additional tufts of grass (randomly determined). If a fully grown grass tile succeeds a growth check, it will check all 4 adjacent tiles. If they are tillable, there is a 25% chance for each tile for 1-2 tufts of grass to grow.[5]

On the 1st of spring in year 2+ there will be 40 iterations of growth checks of all grass tiles.[6]
