What Are Mutations in Grow a Garden?
Mutations are special upgrades for your crops that change their stats and increase their profitability. Each mutation is unique, but most of them act as multipliers—boosting how much Sheckles you can earn from selling crops.
- Basic mutations are usually easy to get from pets or simple combinations.
- Advanced mutations, like Blazing and Meteoric, require combinations of other mutations or access to rare pets/events.
- Infernal is a “fusion mutation,” meaning it can only be created by combining two advanced ones.
How to Get the Infernal Mutation
Before you can create Infernal, you need two specific mutations: Blazing and Meteoric. Once you have them, you can fuse them on a crop to unlock Infernal.
Here’s a detailed breakdown of each step:
| Mutation | Requirements & How to Obtain |
|---|---|
| Flaming | Only obtainable from the Phoenix pet (limited-time). |
| Molten | Can be obtained from the Volcano Admin Event or the Lobster Thermidor pet. |
| Blazing | Combine Flaming + Molten. |
| Meteoric | Available during a Meteoric Strike Event or through the Lobster Thermidor pet. |
| Infernal | Fuse Blazing + Meteoric on a crop in your garden. |
Step-by-Step Process
- Get the Phoenix pet (or borrow it if trading is enabled on your server). This is the only way to get the Flaming Mutation.
- Participate in the Volcano Admin Event or secure the Lobster Thermidor pet to gain Molten.
- Combine Flaming + Molten → Blazing Mutation.
- Wait for a Meteoric Strike Event (or use Lobster Thermidor again) to collect the Meteoric Mutation.
- Combine Blazing + Meteoric → Infernal Mutation.
What Does the Infernal Mutation Do?
Once unlocked, Infernal adds a ×190 multiplier to the value of your crops. This means every time you sell your harvest, you’ll earn 190 times more than the base value.
Why is this important?
- It’s one of the highest multipliers currently in the game.
- It dramatically speeds up Sheckle farming, letting you buy more pets, expansions, or upgrades faster.
- It’s a great long-term investment for competitive players aiming to climb leaderboards.
Tips & Strategies for Unlocking Infernal
- Time your events: The Meteoric Strike and Volcano Admin Events don’t happen often, so keep an eye on event schedules.
- Focus on pets early: Both Phoenix and Lobster Thermidor are crucial. Without them, you’ll struggle to complete the chain.
- Use crop slots wisely: Don’t waste crop slots on weaker mutations once you’re chasing Infernal—save space for the required fusions.
- Trade or borrow pets: If your version of the game allows trading, this can save you weeks of grinding.
- Prioritize Infernal over others: While there are fun mutations, Infernal’s ×190 boost makes it one of the most efficient for profit farming.
The Infernal Mutation is a late-game powerhouse in Grow a Garden. It requires patience, event participation, and rare pets, but the payoff is enormous. With its ×190 multiplier, Infernal can turn even modest crops into massive Sheckle producers, making it an essential target for serious players.
