Acorn

This can be planted to grow an oak tree.
Overview
Acorn is a seed that grows into an Oak Tree. It can be found by shaking or chopping down Oak Trees once Foraging level 1 is reached, searched from Garbage Cans, or dug up with an Axe or Pickaxe after a fully grown Oak Tree drops one on The Farm. In a Woodskip Fish Pond, one to five acorns can also be produced once the pond population reaches 9.
Acorns can be planted in tillable ground outside The Farm, but the tile must be un-tilled before planting. Like other tree seeds, an acorn grows through five stages. During Spring, Summer, and Fall, it has about a 20% chance to advance one stage each night, with a median maturity time of roughly 18 days and more than 90% of seeds reaching maturity within 32 growing days. 
Acorns have several uses beyond planting:
- Ten Acorns may be selected as one of the Community Center bundle options.
- They can be used in the
Sewing Machine spool to create clothing.
- They can be placed in dye pots in
Haley's and
Emily's house as an orange dye.
- Several Fish Pond quests may request two or three Acorns.
