Pour this onto compost to make it into super-compost.

Compost potions (also known as Supercompost potions) are used to make supercompost. Players may use a dose on bucket of compost to make it into supercompost, or use a dose on a full Compost Bin to obtain 15 supercomposts. A compost potion is one of the quest rewards after completing Garden of Tranquillity, it can also be purchased with reward points from participating in the Nightmare Zone minigame. This potion cannot be made with the Herblore skill.

Players are advised to use these potions for their own compost bins instead of selling them away, as they will earn more by making buckets of supercompost. Note that the player cannot add a dose of compost potion to compost bins containing a combination of normal compost and supercompost vegetation (in any combination).


  • This potion is one of the few in the game that you cannot drink.
