How to Obtain Grimy Dwarf Weed

There are several ways to acquire Grimy Dwarf Weed in OSRS, ranging from Farming to PvM drops and minigames. Each method has its own requirements and benefits, so let’s break them down.

Farming Dwarf Weed

Growing Grimy Dwarf Weed is one of the most reliable methods for obtaining it, especially for players with high Farming levels. You’ll need a Farming level of 79 to plant a Dwarf Weed seed in a herb patch. Here’s how it works:

Seeds: Dwarf Weed seeds can be obtained from monster drops (e.g., Nechryaels), pickpocketing Master Farmers, or purchased from the Vinesweeper minigame for 9,000 points each.
Harvest Yield: Each fully grown Dwarf Weed plant yields a minimum of 3 Grimy Dwarf Weeds, with additional lives added by using compost (1 for regular, 2 for supercompost, 3 for ultracompost).
Experience: Planting grants 170.5 Farming XP, and each harvest gives 192 Farming XP.

Tip: Use ultracompost to maximize yield and protect your plants, as gardeners won’t watch over Dwarf Weed patches.

Monster Drops

Grimy Dwarf Weed is a common drop from high-level monsters, making PvM a viable source. Some notable monsters include:

Monster	Combat Level	Location	Drop Rate
Nechryaels	115	Catacombs of Kourend, Slayer Tower	Common
Abyssal Demons	124	Slayer Tower, Catacombs of Kourend	Uncommon
Chaos Druids	13	Edgeville Dungeon, Taverley Dungeon	Rare

Pro Tip: Nechryaels are particularly efficient for herb farming, especially for Ironmen or Ultimate Ironmen seeking consistent seed and herb drops.

Other Sources

Sorceress’s Garden Minigame: Offers Grimy Dwarf Weed as a reward, ideal for players with decent Thieving levels.
Pest Control (Herb Packs): Costs 30 Commendation Points and includes a chance for Grimy Dwarf Weed.
Temple Trekking/Burgh de Rott Ramble: Red token rewards may yield Grimy Dwarf Weed.

Uses of Grimy Dwarf Weed

Grimy Dwarf Weed’s primary value lies in its transformation into Clean Dwarf Weed, which is used to craft powerful potions. Let’s explore its main applications.

Crafting Ranging Potions

The most common use of Clean Dwarf Weed is to create Ranging Potions, which boost a player’s Ranged level by 10% + 3 (rounded down). Here’s the process:

Clean the Grimy Dwarf Weed (requires 70 Herblore, 13.8 XP).
Add the Clean Dwarf Weed to a vial of water to create a Dwarf Weed Potion (unf).
Combine with a Wine of Zamorak to finish the Ranging Potion (162.5 Herblore XP).

Ranging Potions are in high demand for PvM activities like raids and bossing, making this a profitable Herblore training method.

Other Potions (RuneScape Context)

In the broader RuneScape universe (not OSRS-specific), Clean Dwarf Weed is used to craft Super Ranging Potions and Extreme Strength Potions. While these aren’t available in OSRS, it’s worth noting for players exploring both games or planning future updates.

Supercompost

Grimy Dwarf Weed can be used in a Compost Bin to create supercompost, though this is less cost-effective compared to alternatives like pineapples. It’s a niche use for excess herbs.

Money-Making with Grimy Dwarf Weed

Cleaning Grimy Dwarf Weed and selling the clean version on the Grand Exchange is a popular money-making method due to the herb’s high demand. Here’s how to approach it.

Degriming Profitability

Cleaning Grimy Dwarf Weed can yield a profit of around 300–500 coins per herb, depending on market prices. Key considerations include:

Buy Limit: 11,000 Grimy Dwarf Weeds every 4 hours.
Inventory Speed: 27–28 herbs can be cleaned per inventory, taking 10–20 seconds.
Profit Check: Always verify live prices on the Grand Exchange, as margins fluctuate.

Warning: Test the market with a small batch before investing heavily, as price crashes can erode profits. Using mouse keys can speed up the cleaning process and reduce strain.

Farming for Profit

Farming Dwarf Weed seeds is another lucrative option. With ultracompost and high Farming levels, you can expect 6–10 Grimy Dwarf Weeds per patch. At 1,000–1,500 coins per herb (based on historical GE prices), a single run across multiple patches can net significant profits.

Input	Cost (Approx.)	Output	Revenue (Approx.)
1 Dwarf Weed Seed + Ultracompost	2,000–3,000 coins	6–10 Grimy Dwarf Weeds	6,000–15,000 coins

Tip: Combine herb runs with other high-yield crops like Snapdragon for maximum efficiency.

Tips and Tricks for Maximizing Grimy Dwarf Weed

To make the most of Grimy Dwarf Weed, consider these advanced strategies:

Optimize Herb Runs

Use teleports (e.g., Explorer’s Ring, Ardougne Cloak) to access herb patches quickly. Equip the Farming Cape for a chance to double herb yields if you’re level 99.

Stack with Slayer

Assign tasks like Nechryaels or Abyssal Demons to combine Slayer training with herb and seed collection. Use a Herb Sack to store Grimy Dwarf Weeds without banking.

Market Timing

Monitor GE Tracker for price trends. Sell Clean Dwarf Weeds during peak demand (e.g., after major PvM updates) to maximize profits.

Ironman Strategies

For Ironmen, focus on Nechryael tasks or Sorceress’s Garden for consistent herb supplies. Store excess herbs in a Herb Box at the Nightmare Zone for later use.

Conclusion: Grimy Dwarf Weed is a cornerstone of high-level Herblore and Farming in OSRS, offering both skill progression and profit potential. Whether you’re farming it, cleaning it for profit, or crafting Ranging Potions, this herb is a versatile asset. By leveraging the strategies in this guide, you can turn Grimy Dwarf Weed into a reliable source of XP and gold. Happy herbloring!
