An oak seedling is created by sowing an acorn in a plant pot filled with soil with a gardening trowel, granting 1.2 Farming experience. Once watered, it will turn into an oak seedling (w), which will grow into an oak sapling. However, while the seedling is growing into a sapling, it is possible to salvage the acorn from the plant pot, granting another 1.2 Farming experience. Salvaging the acorn can fail, but uncommonly. An oak sapling requires level 15 Farming to plant in a tree patch.
