Wailmer Pail
From Pixelmon Wiki
The Wailmer Pail is used for advancing the growth of Apricorn trees by a stage. It can only be used occasionally, and attempts to water an already-watered tree will fail and give the message "It looks well watered today."
Formerly, in Pixelmon 2.3, the Wailmer Pail was used as unlimited bone meal. The Wailmer Pail no longer works like bone meal in Pixelmon 2.5.
It is crafted using 3 Bones (collected from Cubone and/or Marowak) along the top, a Water bucket in the center and three Iron Ingots along the bottom.
