Bone Meal can be used as dye as well as fertilizer for most plants. After crafting bone meal, there will be new recipes unlocked for you.
You just need Skeleton Bone and Crafting Table to make Bone Meal. Please follow the following steps to make a Bone Meal.
In order to make bone meal, the basic item that you will need to get is skeleton bone. You will have to find and kill a skeleton using your sword to get at least one bone. Skeletons randomly drop bones when they die.
Now you need to use the crafting table to craft bone meal. So move towards the crafting table and open up 3*3 crafting grid to add a skeleton bone in the center or any cell of the grid. You will get three bone meals in the right-side box to the crafting table. Add these bone meals in your “ready to use” stock.
