Grow a Garden Mutation Multipliers: Exact Values for Every Mutation (2026)

✅ Last Verified: April 2026. All values sourced directly from game data. If a patch changes any multiplier, report it in our Discord and we'll update within 24 hours.

The most common question in any Grow a Garden Discord: "What does [mutation] actually do?" Followed immediately by a half-dozen answers that disagree on the number. This page exists to end that argument. Every multiplier below is pulled directly from the game's mutation data — not estimated, not crowd-sourced, not copied from a wiki that cited another wiki.

Use this as your reference during farming sessions. If you want to simulate specific stacking combinations, our Crop Calculator uses the same underlying values.

Standard Mutations (Environmental / Weather-Triggered)

Standard mutations roll based on active weather events and day/night cycle. They are stackable — multiple Standard mutations can appear on the same crop and multiply together.

💡 Pro Tip: Shocked (100x) is the most accessible top-tier mutation in this table — it's triggered by standard Thunderstorm weather with no event pass or limited pet required. Raiju and Firefly pets increase your roll rate during storms. If you're building a weather farming strategy, Thunderstorm sessions are the highest guaranteed ROI.

Variant Mutations (Pet and Fertilizer-Triggered)

Variant mutations change the visual appearance of a crop and add a multiplier on top of any Standard mutations already present. Only one Variant can appear on a crop — they don't stack with each other.

💡 Pro Tip: Rainbow requires 5 or more other mutations to already be present on the crop at harvest. This makes it a reward for successful weather stacking — not a standalone strategy. Farm your Standard mutations first; Rainbow lands on top if the conditions are met.

Fused Mutations

Fused mutations activate when two specific base mutations appear together on the same crop. The fused version replaces both source mutations. Whether that's an upgrade depends on the math — see the table below.

💡 Pro Tip: Cosmic and Abyssal look impressive but are traps. If you're farming Celestial + Aurora sessions (e.g., during Crystal Beam weather), you don't want them to fuse. To prevent the Cosmic fuse, avoid pet combinations that simultaneously boost both Celestial and Aurora rolls — or accept the trade-off if Cosmic has higher trading value to you than raw Sheckle output.

Limited Mutations (Event Weather, Special Pets)

Limited mutations are only available during specific events, admin-triggered weather, or via pets that aren't always accessible. They follow the same stacking rules as Standard mutations.

Negative Mutations

Not all mutations are beneficial. Negative mutations reduce crop value and should be avoided through careful pet selection and timing.

FAQ — Mutation Multiplier Questions

What is the highest mutation multiplier in Grow a Garden?

Dawnbound at 150x is the highest individual Standard mutation. Among Fused mutations, Cosmic and Abyssal both sit at 240x — but both replace source combinations that stack to significantly higher values (10,800x for Cosmic's sources). In terms of achievable stacked multipliers, the ceiling is well above any single mutation value.

Is Plasma a high-value mutation?

No — Plasma is a Limited mutation worth only 5x. It's commonly confused with being more powerful because of its visual effect, but it's equivalent to Twisted or Drenched in multiplier value. Don't rearrange your pet loadout around Plasma farming; focus on Shocked (100x) from Thunderstorm instead.

Does Celestial really give 120x?

Yes — Celestial is 120x, triggered by Meteor Shower and Crystal Beam. It's commonly listed as 100x on community wikis that copied an outdated value. Our data is sourced from the game's current mutation file.

Can two Variant mutations appear on one crop?

No. Only one Variant mutation (Gold, Rainbow, Diamond, or Silver) can appear on a single crop. If you're running both a Gold Fertilizer and a Rainbow-boosting Butterfly pet, only one Variant will land.

How do I get Dawnbound?

Dawnbound (150x) comes from Sun God weather and Ascended-tier pets. It's one of the rarest Standard mutations in the game because Sun God weather isn't a standard rotation event. Focus on Celestial and Shocked farming for consistent top-tier multipliers.
