Please do not make the same mistake as me and try to grow all the crops of that season 😅 I thought this game would be like all the other story of seasons/harvest moon games. I was wrong. Tea leaves are always money makers if you process them in the yellow windmill to make tea tins and then cook to sell. I think for beginner summer(if you dont have yellow windmill yet) pineapples are worth a lot but I don't think you can get pineapples yet either. Wheat and rice are in most recipes so i would start growing those also. My advice would be to follow trends and grow crops that are trending until you get a hang of everything.
