Nether Wart is a plant that can only be contained in the Nether in its natural state. Only in Nether fortresses, chests, and near such staircases you may find it, and only soul sand can it grow. Nether Wart can be used to make Awkward Potions in the brewing process. The awkward potion, which is used in the base of almost all potions, requires Nether wart to be brewed. Except for potions of weakness, all potions must be made from scratch. In return for emeralds, cleric villagers will purchase Nether wart.
Before we can start making nether warts, we must get some of them.
Nether warts will appear in nether fortresses near stairwells in soul sand gardens, and can also generate in the courtyards of housing unit bastion remnants. They only produce in around 0.1 blocks per chunk because they are only contained in rare nether fortresses and housing unit bastions.
As you can see from the picture above, the nether wart is growing at the sides of the stairs in the nether fortress. Several of these patches are locates near the staircases.
Every section of the piglin housing unit bastions has a patch of nether wart growing in the central courtyard.
Now that you have located the nether wart growing in each of these locations, you can harvest them. They can be mined instantly with any tool. A mature nether wart crop yields 2 to 4 nether warts, which can be increased by one for each level of Fortune. All other stages drop 1 nether wart, regardless of whether Fortune is used.
Given the importance of nether wart in the brewing of nearly all types of potions, it's a good idea for players to set up a farming operation to get their brewing ingredients quickly. The growing time is randomized, much like all the other crops.
Start by placing soul sand in your garden. While Nether Wart can be planted in the normal world, it will not grow unless planted on soul sand.
Next, plant the Nether Warts in the soul sand which can be done by simply right clicking the soul sand with the nether wart equipped in the hotbar slot.
Pick up the Nether Warts and put them in your inventory. The Nether Warts can then be replanted in the soul sand to expand even further similar to other crops.
Nether warts grow in four stages when planted on soul sand, but the middle two stages are nearly identical. They have a 10% chance of rising one stage with each random tick. Light and other environmental factors have no effect on the rate of development. Nether warts cannot be treated with bone meal.
Congratulations! You have successfully mined and farmed Nether wart. Nether Wart can be used to make Awkward Potions in the brewing process. The awkward potion, which is used in the base of almost all potions, requires Nether wart to be brewed.
