Food is a constant need for Founded players. You have to eat food regularly, but it can be a bit boring. To get it, you need to either eliminate the bugs or make do with acorn pieces and basic mushrooms. Creating a mushroom garden is a great way to make sure you always have food on hand before you go on an adventure with your friends.
You can learn the Mushroom Garden recipe after finding an acorn top. These usually fall closer to the oak tree, so you want to go east of the initial spawn and look around the area. It takes a pebble hammer or better to break it and collect the pieces. To create the Mushroom Garden, you need four ingredients: eight woven fibers, six weed stems, an acorn top, and rotten meat.
Woven fibers are a common item to meet and craft in the game from the various grass fibers that you can find almost anywhere. The weed stems are a bit more delicate. You need to find a dandelion plant, treat it the same as a stalk of grass, and cut it down. The weed stems will be on the ground and you can bring them back to your camp. You can use the acorn top you scanned for the project, or find more at the base of the oak. The final item, Rotten Meat, is something you can have by hanging onto any form of Insect Meat and then letting it sit in your inventory or chest for a full day in the game. will become spoiled and you can use it in your garden.
Once you have all the ingredients, place your mushroom farm near your camp and visit it every now and then to pick mushrooms. While not the best food to eat, it is an available item that you can take with you wherever you go.
