2 Forest ambassadors on your forest giant. Then go to the forest landscape and create a plant, give it a fruit aspect and upgrade from there (x2).Caiobrz wrote: That!
Also, a tooltip on how to unlock some sources would be nice. I'm still lost on how to get "pear trees" T_T
Or the slightly more micro intensive but much quicker way is to have a single forest ambassador on your forest giant.
Then, create a plant on the landscape, use the fertility boost on that square and then add a fruit (this should now be a potent fruit). Then upgrade it twice (first to apple tree, then to pear tree).
It's one of my favorites so I know it by now ;)
