Moss
A special type of plant that grows in shady areas.
Overview
Moss is a forage-like item associated with trees and Green Rain. It can grow on fully grown Oak Trees, Maple Trees, Pine Trees, and Green Rain Trees of type 1 or 2, provided the tree is at least growth stage 14. At the start of each day, eligible trees can gain Moss based on weather and season: the chance is 10% on sunny days, drops to 3.3% in Summer, and is 20% on rainy days. During a Green Rain, any tree that can grow Moss will gain it immediately, regardless of growth stage.

Moss has several practical uses. It can be selected as one of the options for the Community Center bundle that accepts ten Moss. It is also requested in quests: the Raccoon at the Giant Stump may ask for ten Moss as part of his fifth request, and it can appear in any request from the sixth onward.

- It is tied to tree type and growth stage, so young or ineligible trees will never produce it.
- Rain improves the daily growth chance, while Summer reduces the sunny-day rate.
- Green Rain is the fastest way to get Moss on eligible trees.
- Winter clears Moss from trees outside the Greenhouse, so stockpiling before Winter can help if you need it for quests or crafting.
