Stardew Valley is no doubt an ideal place for farming. The rich loam soil covering most of your farm has all the qualities to grow crops. Add a dash of fertilizer, and that soil can cultivate the best-tasting fruits and veggies in the valley. Fertilizers are purchased from various shops, but you can make some on your own using a Bone Mill. This guide will teach you how to use the Bone Mill machine properly.
Crafting the Bone Mill in Stardew Valley
The Bone Mill refining machine can make fertilizer from bones and artifacts. It is a piece of equipment you can build using different raw resources. Getting to a specific player level is not a requirement to learn how to craft the Bone Mill. Its recipe is not available in any store or any festival booth. You can only earn it by completing the Special Boards Quest: Fragments of the Past.
To make a Bone Mill, you will need the following items:
- 20 Stones
- 3 Clay
- 10 Bone Fragments
Stones and Clay are the easiest to obtain; you will only need a few to craft one Bone Mill. Bone Fragments are commonly found on the Ginger Island Dig Site. The Dig Site has Bone Nodes that spawn everywhere in that area. These nodes drop a couple of Bone Fragments when you break them.
Getting Bones for the Bone Mill
The Bone Mill takes in different bones and grinds them into fertilizer. If you want excessive fertilizers, keeping a pile of remains in your chest is best. Here are the locations of various bone items, fossils, and artifacts spread throughout the valley:
The Mines: Defeating Skeletons
Quarry Mine: Defeating Haunted Skulls
Outside the Mines: Digging up Artifact Spots, Fishing Treasure Chests
Skull Cavern: Mining, Destroying Barrels and Crates, Defeating Pepper Rexes
Ginger Island: Mining, Digging up Artifact Spots, Defeating Lava Lurks, Panning, Fishing Treasure Chests
Before the Bone Mill came with the 1.5 game update, fossils were donated to the museum or displayed on your farmhouse. Now, you can use them to produce fertilizers. Here is the list of assorted items you can put in the Bone Mill:
Amphibian Fossil
Bone Fragments
Fossilized Leg
Fossilized Ribs
Fossilized Skull
Fossilized Spine
Fossilized Tail
Mummified Bat
Mummified Frog
Nautilus Fossil
Palm Fossil
Prehistoric Rib
Prehistoric Scapula
Prehistoric Skull
Prehistoric Tibia
Prehistoric Vertebra
Skeletal Hand
Skeletal Tail
Snake Skull
Snake Vertebrae
Trilobite
Note that five Bone Fragment pieces are required to produce fertilizer. Aside from that, you must only put one bone item into the Bone Mill to make it work.
How to Use The Bone Mill in Stardew Valley
The Bone Mill functions like any other piece of equipment in the game. Take out an item from your inventory, put it into the machine, wait for four in-game hours for the item to process, and you will get packs of fertilizers. The Bone Mill spits out different types of fertilizer, but you will get a random one each time you use it. You can even obtain more fertilizers than usual if you get lucky.
Here are all the types of fertilizers the Bone Mill can produce. This list also includes the number of packs you can obtain:
- 3 packs of Deluxe Speed-Gro
- 10 packs of Quality Fertilizer
- 5 packs of Speed-Gro
- 5 packs of Tree Fertilizer
Now that you know how to use the Bone Mill, you can save all that money you would spend on packs of fertilizers and use all the ancient bones you can collect in the game.
