Farming/Patch locations

Limpwurt only patch
There is a flower patch in the Wilderness that can only be used to grow limpwurt seeds.

Allotment only patch
There is a single allotment patch on Harmony island. The Great Brain Robbery quest must be completed to access it.

Potato only patch
There is a patch used exclusively for potatoes located next to the flax field in Taverley. Head Farmer Jones trades you 3 potato seeds for free and automatically looks after your crops as a gardener, so you cannot water your patch; you can, however, use compost or supercompost to increase your harvest load. There is a leprechaun tool store next to it and there is a compost bin. This patch cannot get diseased.

Herb only patches
Except for the ones listed below, all other herb patches are located at the above locations (allotment patches).
