Mutations (also known as Modifiers) are special effects in Grow a Garden that apply to fully grown crops.
These are triggered during certain weather events or through items like pets and gear.
The main benefit is that they boost the crop’s sale value using multipliers.
Mutations stay active until the crop is harvested, giving you the chance to sell it strategically.
Each mutation gives crops a unique look, such as glowing or aura effects, and has its multiplier, making these crops highly valuable for both selling and trading.
To calculate the final value of a mutated crop, the game uses this formula:
Total Price = Fruit Constant × Mass² × Growth Mutation × (1 + ∑Mutations − Number of Mutations)
