|Examine||A marrentill seed - plant in a herb patch.|
A nearby gardener will not watch over your growing marrentill.
Grimy marrentills are the cheapest herbs in RuneScape. Supercompost or Fertile Soil spell is strongly advised against, as although this is the best way of preventing your herbs from getting disease, and it is not possible to water the patch or ask a farmer to tend the herbs, they both cost far more than the maximum yield of herbs.
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 -12 coins.
|Herb yield||Profit/loss||Herb yield||Profit/loss|
Note: Supercompost yields a minimum of 5 herbs.
|Healthy Marrentill plant|
|1||The seed has only just been planted.|
|2||The herb is now ankle height.|
|3||The herb is now knee height.|
|4||The herb is now mid-thigh height.|
|5||The herb is fully grown and ready to harvest.|
This herb plant, like all others herb plants, does not require watering and will grow on its own.
