Mushroom Log Unlock and Crafting
Unlock / Foraging Level 4, Hardwood, and Moss
Mushroom Logs unlock at Foraging Level 4 and turn Hardwood plus Moss into a repeat mushroom source. Build them after Green Rain or Moss stockpiles are stable, then place them near non-fruit trees.
Harvest Rhythm
Timing / 4-day production and rainy-day speedup
Mushroom Logs produce every 4 days, and rainy days reduce the wait by one day. They work in all seasons and can produce in the Desert and on Ginger Island.
7x7 Tree Radius
Layout / Nearby non-fruit trees and 5-mushroom cap
Mushroom Log quantity scales with non-fruit trees in a 7x7 square around the log, including immature trees. Around 10 nearby trees is enough to always reach the maximum quantity of 5 mushrooms.
Tree Type Planning
Mushroom Type / Oak Morels, Pine Chanterelles, Maple red or purple, Mystic purple
Nearby mature trees influence mushroom type: Oak supports Morels, Pine supports Chanterelles, Maple leans Red Mushrooms with a smaller Purple chance, and Mystic Trees push Purple Mushrooms.
Quality and Moss Scaling
Quality / Mossy trees, quality upgrades, and Botanist exception
Mushroom quality is based on nearby trees and mossy trees, not the Botanist profession. Mossy trees count more heavily, so a mature mossy grove improves output quality over time.
Dehydrator Route
Artisan / Dried mushrooms and low-touch processing
Mushroom Logs feed Dehydrator routes once the farm produces more mushrooms than cooking, gifts, bundles, or Raccoon requests need. Group logs, chests, and Dehydrators into one simple loop.
