- Not to be confused with the Spirit seed.
Spirit weed seeds can be planted in a herb patch in order to produce Grimy spirit weed herbs. This requires a Farming level of 36. Spirit weed seeds can be obtained as a monster drop, from Managing Miscellania if your workers are assigned to Farming or cleaning out a bird's nest.
A nearby gardener will not watch over your growing spirit weed.
Growing the herb
Planting spirit weed seeds are very profitable, therefore players are advised to make sure that the herb does not die. Supercompost (or Fertile Soil spell) is strongly recommended, as this is the best way of preventing your herbs from getting disease, as it is not possible to water the patch, or ask a farmer to tend the herbs. It is highly recommended to use My Arm's herb patch, because he will protect your herbs from death for free, but you must first complete My Arm's Big Adventure.
Profit
The following table shows the profit yield, assuming all the herbs and seeds are purchased/sold at the Grand Exchange, for the guide price. If the herb dies, you will lose

Trivia
