Gardener Gunnhild is one of the subjects players must get support from in Throne of Miscellania. She is just outside the south-east corner of Miscellania castle. She sells iron sickles and rakes.
You need her support during Throne of Miscellania; after the quest's completion, you can assist her to gain favour. Players usually choose to assist Gardener Gunnhild to increase their popularity since she's right on the way to Advisor Ghrim. Players need a rake to use on the flax/herb patch; a rake on a toolbelt works. Every weed weeded earns 1% popularity, or more if the Fremennik Hard Tasks are complete. Gardener Gunnhild is one of four residents whom you can assist to gain favour; the other three are Miner Magnus, Lumberjack Leif, and Fisherman Frodi.
Her animation for raking was changed in a hidden update on 14 August, 2012. Currently, she is the only NPC to use this new animation.
When players were at 99% popularity, and they rake the patch, it was possible to get 102% as she does not stop players when they weed more than needed. She still does not stop players when they weed more than need but doing so will not result in 102%.
