Fertilizer

When visiting a neighbor's farm, a farmer can choose to fertilize their crops, and be awarded experience and coins for doing so. After helping out a neighbor, a farmer is able to fertilize 5 crops. Originally, fertilizer could only be used on crops that were under 90% grown; as of the 17th December, farmers can fertilize fully grown crops or bare patches of soil (but not fallow land).

Items from Collections can sometimes be found while fertilizing.
