Where're the crops?! Searching the world for seed wisps on Nintendo Switch, Steam Ps4, and Xbox. [ Game Guide ] JP release = None. NA release = Mar 2021. EU release = Mar 2021.
I've had similar issues with that crop mutation. I've tried growing Heart of the Earth in the Lebkuchen lava field during summer, fall, and winter, and have had no luck. I haven't tried spring season yet.
Okay, I found Giant's Heart. At least for the girl version, you have to get it in summer in the volcano field in Lebkuchen. Plant on a sunny day. Harvest on a sunny day, and use fertilizer. I am so happy! Finally!
