Stardew Valley Mushroom Log
Mushroom Log guide for Foraging Level 4 crafting, Hardwood and Moss costs, 7x7 tree radius, 4-day harvest rhythm, rainy-day speedup, tree type mushroom rules, moss quality scaling, and Dehydrator routes.
Quick facts
Mushroom Logs unlock at Foraging Level 4 and cost Hardwood plus Moss.
They produce mushrooms every 4 days, with rainy days reducing the timer by one day.
Nearby non-fruit trees in a 7x7 square improve quantity, while mature tree types influence mushroom type.
Build the grove
A Mushroom Log is strongest when treated as part of a grove layout. The log checks nearby non-fruit trees, so a planned 7x7 area is better than random placement.
- Use around 10 nearby trees to reliably reach the maximum 5-mushroom output.
- Use Oak, Pine, Maple, or Mystic Trees depending on the mushroom type you want more often.
- Keep logs close to chests and Dehydrators so harvesting does not become a chore.
Plan quality and use
Mushroom Log quality depends on nearby trees and moss, not the Botanist profession. Keep some mossy trees in the grove if better quality matters.
- Reserve mushrooms for Exotic Foraging, Life Elixir, gifts, Raccoon requests, and cooking before bulk processing.
- Use Dehydrators when the mushroom supply becomes larger than direct demand.
- Use Green Rain and Mossy Seed planning to support long-term Mushroom Log materials.
