Super Compost Requires Baskets, Compost, and Specific Items

Super Compost is made by adding one of four items to a basket of regular compost. You need a compost basket (which holds 10 charges of regular compost), one of the four boost items, and access to a compost bin. The four items that create super compost are: volcanic ash, wood ash, blood rune, or crushed bird nests. Each produces the same result — one charge of super compost — but volcanic ash is the cheapest and most common choice for players making large quantities.

The process itself is when ready. You add the boost item to the basket of regular compost, and the basket now holds super compost instead. You do not need a specific location, a quest, or a particular skill level beyond what you need to obtain the materials themselves.

Key Takeaways

  • Super Compost is made by adding volcanic ash, wood ash, blood rune, or crushed bird nests to a basket of regular compost.
  • Volcanic ash is the cheapest boost item and is obtained by burning wood at a bonfire or by looting it from volcanic areas.
  • You need a compost basket filled with regular compost before you can add any boost item.
  • The conversion happens when ready and requires no skill level, quest, or special location.
  • Super Compost increases crop yield by 10 percent compared to regular compost when used in farming patches.

Where to Get a Compost Basket

A compost basket is purchased from the Farming Supplies shop in Ardougne, run by the NPC Ghrim. The basket costs 800 coins and holds 10 charges of compost at a time. You can also buy baskets from other farming shops across Gielinor, but Ardougne is the most accessible for most players.

Once you own a basket, you can fill it with regular compost at any compost bin. Compost bins are located in farming patches — Lumbridge, Ardougne, Falador, Catherby, and Hosidius all have them. You can also use the bin in your player-owned house if you have built one.

Getting Regular Compost to Fill Your Basket

Regular compost is made by filling a compost bin with organic waste over the course of several days. Organic waste includes items like bones, meat, fish, vegetables, and herb remains. You deposit these items into a compost bin, and after a set time (usually 24 hours), the bin produces a pile of regular compost that you can withdraw.

If you do not want to wait, you can buy regular compost directly from other players through the Grand Exchange, or you can purchase it from farming shops. The cost varies depending on demand, but regular compost is one of the cheapest farming supplies in the game.

Volcanic Ash: The Cheapest Boost Item

Volcanic ash is the most cost-effective way to make super compost. You obtain it by burning logs at a bonfire — any type of log works, though cheaper logs like oak or willow are preferred since you only need the ash, not the experience. Each log burned produces one volcanic ash.

Alternatively, you can loot volcanic ash directly from volcanic areas in the Catacombs of Kourend or purchase it from the Grand Exchange. If you are making large quantities of super compost, buying ash in bulk from the Grand Exchange is often faster than burning logs yourself, though the price fluctuates.

Other Boost Items and When to Use Them

Wood ash is obtained by burning logs in a fireplace or by looting it from certain areas. It works identically to volcanic ash but is slightly more expensive on the Grand Exchange. Blood runes are purchased from the Grand Exchange or obtained through runecrafting, and they are significantly more expensive than ash — most players avoid them for compost-making.

Crushed bird nests are made by using a pestle and mortar on bird nests, which are looted from trees or purchased from the Grand Exchange. Like blood runes, they are more expensive than ash and offer no advantage over it. Volcanic ash remains the standard choice for cost-conscious players.

How Super Compost Improves Your Crops

Super Compost increases the yield of crops by 10 percent compared to regular compost. This means more produce per harvest across all farming patches. The boost applies to every crop type — vegetables, herbs, fruits, and trees all benefit equally.

For players running herb runs or managing multiple patches, the yield increase compounds over time. A herb patch that normally produces 5 herbs per harvest will produce approximately 5 to 6 with super compost. Over dozens of harvests, this adds up to meaningful profit or resource gains.

Frequently Asked Questions

Can I make super compost without a compost basket?

No. You must have a compost basket filled with regular compost before you can add a boost item. The basket is the container that holds the compost and allows the conversion to happen.

Do I need a specific Farming level to make super compost?

No. Making super compost requires no skill level. However, you do need a Farming level to use it in patches — most patches require 1 to 45 Farming depending on the crop type.

What is the fastest way to gather volcanic ash?

Buying volcanic ash from the Grand Exchange is fastest if you have the coins. If you prefer to gather it yourself, burning cheap logs like oak or willow at any bonfire is straightforward, though it takes time for large quantities.

Does super compost work in all farming patches?

Yes. Super Compost increases yield in every farming patch — allotments, flowers, herbs, hops, and trees. The 10 percent boost applies universally.

Can I store super compost in my bank?

Yes. Compost baskets can be banked like any other item. You can carry multiple baskets and withdraw them as needed for different patches.
