Compost potions are made by mixing harralander and volcanic ash in a vial of water. Doing so requires level 22 Herblore and gives 60 experience.

A compost potion is one of the quest rewards after completing Garden of Tranquillity, and can be purchased with 5,000 reward points from participating in the Nightmare Zone minigame.

Players can use a dose of compost potion on a bucket of compost to make it into supercompost, or use a dose on a full compost bin to obtain 15 buckets of supercompost instead. It can also be used on Big Compost Bin which turns all 30 buckets of compost into super with a single dose, thus doubling the potion's benefit.

Trivia

Volcanic ash has been valued as a real-world fertilizer for over 2,000 years, which gives this potion historical realism.
This potion is one of the few in the game that players cannot drink.
Prior to the release of the Nightmare Zone, compost potions were only obtainable as a one-time reward from completing the Garden of Tranquillity quest.
