Requirements
The Propagator isn't immediately available – you'll be given the recipe when you have a farmhouse cellar and a mushroom cave!
Demetrius will visit the morning after Robin finishes your cellar to deliver the recipe.
Unless changed in the config, the propagation log isn't available with a fruit cave!
Crafting
Logs are crafted with the same ingredients as a cask – 20 wood and 1 hardwood!
Place a mushroom on the log to start growing!
Growing
At the end of the day, each of the logs will grow a little more.
A common mushroom will typically grow every night, a red mushroom every two nights, and a purple mushroom every four nights.
Custom mushrooms added with Json Assets, like Shiitake Mushrooms and Black Fungus, will grow relative to their value.
You can leave the logs for a few days and they'll keep growing more mushrooms for their stacks for when you check on them.
The logs can only hold so many of each type of mushroom, though: bigger and better mushrooms will grow smaller stacks.
Keep an eye out for logs with huge, fully-grown mushrooms: they've reached their capacity, and you'll need to pop them off to keep growing.
Interacting
Click a log while holding a mushroom to add it as the root-mushroom. If the log's no
Adds a new craftable rotten log that grows mushrooms overnight, obtained from Demetrius after Robin builds the cellar. A popular gameplay mod with 1,470 endorsements and 46,373 downloads, last updated August 2025.
