Mutations are special effects added to crops and are a key part of Grow a Garden.
They mainly help by boosting the crop’s value, allowing players to earn more Sheckles and profit.
The game features many types of mutations, such as Meteoric, OldAmber, and Voidtouched, which random weather events, specific pets, or gear can trigger.
To calculate the value of a mutated crop, the following formula is used:
Total Price = Fruit Constant × Mass² × Growth Mutation × (1 + ∑Mutations − Number of Mutations)
