It'd be great if we had a Gardening Log that listed information such as time for growth, crossbreeds and results (once we had personally attained them) with some lore tidbits in the same way the Fishing Log/Minion/Mount Guides. Maybe also a link from the seeds to our Gathering Log so we can quickly see what region to Harvest them from, where applicable.

Also, it seems odd that Achievements for Gardening don't exist. Suggestions for the top-tier achievements in their respective chains:
  • Tend Crops 1,000,000 times
  • Fertilise Crops 1,000,000 times
  • Harvest 100,000 HQ items from gardens
  • Harvest 500,000 items from gardens
  • Crossbreed 100,000 plants
  • Grow 60 different plants

With some nice gardening glamour pieces (let's call it "Scarecrow Attire") as a reward for each!
