The profit calculation above assumes exactly level 57 Farming and no effects that boost yield other than a juju farming potion and ultracompost. Using the crop farmer outfit, a greenfingers aura and the magic secateurs will increase profit further, as will simply having a higher Farming level.
Bloodweed is a rare herb, which can only be obtained by growing it in the herb patch north of the Wilderness Volcano. It is used to make powerful potions, not least of which is the aggression potion, which is very popular among high-level fighters. While any herb except vine herbs can be grown in the Wilderness herb patch, bloodweed is usually the most valuable one.
As ultracompost results in at least one additional herb compared to supercompost, and as grimy bloodweed is worth more than ultracompost, ultracompost should be favoured over supercompost when farming bloodweed. On a similar note, a dose of juju farming potion will pay for itself even if it is used only for one patch's worth of bloodweed.
The fastest way to reach the patch is using the Wilderness sword 1 or one of its upgrades to teleport right to it. Players without access to the Wilderness sword can instead make a waka canoe at a canoe station and travel into the Wilderness using that, although this requires level 57 Woodcutting. If neither of those are possible, running north from the Wilderness volcano lodestone is also an option, although it is slower and more dangerous than either of the others.
Upon reaching the patch, pick the herbs, treat the soil with ultracompost, and plant another bloodweed seed. You will then want to run south until you can teleport, using an item such as the Wilderness sword 4 or an amulet of glory which lets you teleport from level 30 Wilderness - right at the mouth of the Wilderness volcano.
After the elite Wilderness achievements, any herb planted in the Wilderness herb patch is immune to disease.
Although it may be difficult, depending on transportation methods and other patches visited, it is possible to visit this patch after a regular herb run with the buff from your juju farming potion
still active. As you can't teleport directly from this patch, you will likely want to visit this patch as the very last one during a run, as the timer on your juju farming potion will keep ticking down while you run south towards a Wilderness level that allows you to teleport. If doing this, you will likely want to bank your other herbs and other high-value items before visiting this patch, as you risk losing those to player killers
