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 Plagued mutation in Grow a Garden (Roblox) is, its multiplier, how to get it, a wiki, and more.
Grow a Garden Plagued Mutation Multiplier

The Plagued mutation gives crops a 111x multiplier.
It can be applied when a crop has both the Infected and Zombified mutations.
Infected can be obtained during Jandel Zombie while Zombified can be obtained by the Chicken Zombie pet.
The mutation makes crops turn sickly green and emit contagious particles.
