A Yew seed, when planted in a pot, allowed to sprout into a sapling and then planted in a Tree patch, may grow into a Yew tree. Planting the seed gives 81 experience and checking the health gives 7069.9, for a total of 7150.9 experience per seed (unless the tree dies while growing). The farmer will tend a player's yew tree for 10 cactus spines. However, for Yew trees, it is much cheaper on average to just use supercompost and not pay the farmers. Around 1 out of 8 yew saplings will die. In a test of 257 yew trees with no farmer payments, only 36 died.
