Experience Seedling Mod (1.19.2, 1.16.5) adds the seeds from the plant of Experience. To get Experience plant seeds, you need eight gold ingots as well as a wheat seed. A Fortune III enchanted item is enough to collect one seed. The likelihood of getting a single seed drops dramatically if you use an unenchanted tool or if the plant has already matured. You can get the crop without damaging them by using shears that have the right mouse button. This is similar to how you would shear sheep. Beware of villagers: they can destroy your plants… The harvest is made up of Experience Orbs.
You can now use bonemeal on your plants to help them grow but it won’t ripen. You must wait for spontaneous maturation to gain experience.
