In Grow a Garden (Roblox), mutations will increase the value of your crops by a standard multiplier.
They also change the look of your crops, like color, texture, glow, particle effects, and more.
Mutations are triggered when weather events occur, using tools, or planting special seeds.
Most mutations can be obtained automatically when the crop is growing or fully grown.
In this guide, you’ll learn what the Cosmic mutation in Grow a Garden (Roblox) is, its multiplier, how to get it, a wiki, and more.
