How to Build a Nether Wart Farm in Minecraft
Guide to farming nether wart in Minecraft 1.21+. Covers planting on soul sand, growth stages, and why nether wart is essential for potion brewing.
Nether wart is the base ingredient for almost every potion in Minecraft. Awkward potions (made from nether wart + water bottle) are the starting point for strength, speed, healing, regeneration, fire resistance, and most other brewed effects. Farming nether wart ensures a steady supply for all your potion-making needs.
Why build a nether wart farm?
- Required for awkward potions, which are the base for nearly every useful potion.
- Nether wart blocks (crafted from 9 nether wart) are used for decorative building.
- Cleric villagers buy nether wart for emeralds.
- Grows in any dimension, not just the Nether.
Materials list
| Item | Quantity | Notes |
|---|---|---|
| Nether wart | varies | Found in nether fortresses or bastion remnants |
| Soul sand | varies | Required planting surface (soul soil does NOT work) |
| Building blocks | varies | Optional enclosure |
Where to find nether wart
- Nether fortresses: Nether wart grows naturally in stairwell rooms of nether fortresses. These are small gardens with soul sand blocks and planted nether wart.
- Bastion remnants: Some bastion courtyards and gardens contain nether wart growing on soul sand.
Collect as many nether wart as possible on your first visit. You need at least 1 to start a farm, but 9+ gives you a strong start.
Step-by-step build instructions
Step 1: Obtain soul sand
Soul sand is found in the Nether, primarily in soul sand valleys, nether fortresses, and near bastion remnants. Mine it with any tool (shovel is fastest). Soul sand is the only block nether wart can be planted on. Soul soil (a similar-looking block) does not work.
Step 2: Place soul sand in rows
In any dimension, place soul sand blocks in rows. Nether wart does not need water, light, or any specific conditions beyond being planted on soul sand. You can build the farm in the Overworld, Nether, or End.

Step 3: Plant nether wart
Right-click soul sand with nether wart to plant it. Each block gets one nether wart plant. The plant goes through 4 growth stages (visually: small, medium, large with bulbs, fully grown).
Step 4: Wait for growth
Nether wart growth is random-tick based, same as overworld crops. Average maturation time is roughly 30 to 70 minutes at default tick speed. Unlike overworld crops, nether wart is NOT affected by light level, hydration, or biome. It grows at the same rate everywhere.
Step 5: Harvest at full growth
Fully grown nether wart shows large bulbous tops. Breaking it drops 2 to 4 nether wart (average 2.5). Fortune III increases this to 2 to 7 (average 4). Harvesting before full maturity drops only 1 nether wart, which is a net loss.
Key differences from overworld crops
| Property | Overworld crops | Nether wart |
|---|---|---|
| Planting surface | Farmland (tilled dirt) | Soul sand only |
| Water needed | Yes (hydration) | No |
| Light needed | Yes (level 9+) | No |
| Bone meal works | Yes | No (Java Edition) |
| Grows in Nether | No (no water) | Yes |
| Villager auto-harvest | Yes | No |
Automation challenges
Nether wart cannot be auto-harvested by farmer villagers. Villagers ignore nether wart entirely. The only automation options are:
- Water flush: Send a wall of water across the soul sand. Water breaks nether wart on contact and pushes the drops to hoppers. This works in the Overworld but not in the Nether (water evaporates).
- Piston harvesting: Use pistons to push blocks into the nether wart, breaking them. This works in any dimension but requires redstone wiring.
- Flying machine: A slime-block flying machine can sweep across the farm, breaking all nether wart in its path. Collect drops with hopper minecarts below the soul sand.
Replanting must be done manually in all cases. There is no way to auto-plant nether wart in vanilla Minecraft.
Common mistakes
- Planting on soul soil. Soul soil looks nearly identical to soul sand but nether wart cannot be planted on it. Check the block name in F3 to confirm you have soul sand.
- Using bone meal. Bone meal has no effect on nether wart in Java Edition. It is wasted. On Bedrock Edition, bone meal does work on nether wart.
- Harvesting too early. Stage 1 and 2 nether wart only drops 1 item. Full maturity (stage 3) drops 2 to 4. Always wait for the large bulbous appearance.
- Water in the Nether. If you build the farm in the Nether, you cannot use water flush harvesting. Use pistons or harvest manually.
- Not using Fortune III. Fortune III nearly doubles your yield per harvest. Always use a Fortune III hoe or any Fortune III tool when harvesting.
Frequently asked questions
Can I grow nether wart in the Overworld?
Yes. Nether wart grows on soul sand in any dimension. Light, water, and biome do not matter. Place soul sand anywhere and plant nether wart on it.
What potions need nether wart?
Almost all of them. Nether wart brews awkward potions, which are the base for: healing, regeneration, strength, speed, fire resistance, water breathing, night vision, slow falling, leaping, invisibility, and turtle master potions. Only a few potions (weakness, mundane) do not use nether wart.
How much nether wart do I need for a brewing session?
Each awkward potion requires 1 nether wart and 3 water bottles. A brewing stand makes 3 potions at once, using 1 nether wart. For 30 potions (10 brewing batches), you need 10 nether wart.
Can I craft nether wart blocks back into nether wart?
No. Nether wart blocks (9 nether wart = 1 block) cannot be reverse-crafted. The conversion is one-way. Only craft nether wart blocks for building, not storage.
