I love the gardening potions and thought I'd make a route dedicated to the resources used in making them... and then realized it'd be neat to make a route dedicated to resources to make all the potions.
So I went ahead and created it after searching to see if a similar route exists (and if there is one I missed, please let me know and I'll delete mine!).
The requirements are: 2 each bubble and gas trees, at least 30 herb plots and 1 sparkly rock for krazy salt. I also personally have a small crop garden, spice and fruit tree for the ingredients used in purple essence and rainbow potions. Those aren't requirements, just ideas.
Obviously I cannot provide guano, sorry! But I have a still and will leave the hooch out that it produces. Free hooch! LOL
