What is Christmas Mutation
Before learning how to trigger Christmas mutation, you should briefly go through what is it.
Christmas Mutation is a special plant status for Christmas Harvest event. Compared with common mutations, the Christmas mutations can be used to exchange Christmas gifts. Players require submitting the specific mutated plants to Ribbon the Elf or other event NPCs to fill the Christmas bar. If you reach the target points, you will obtain individual or community-based rewards, such as Mega Lollipop. So, the more Christmas mutations you have, the more free rewards you will get.
All Christmas Mutation Types Showcase
The Christmas Mutation is closely connected with the festival and weather. There are five types of mutation. We arrange the mutations below in order based on their difficulty.
- Snowy : The foundational Christmas mutation. The snow occurs every ten minute that turns plants into Snowy type.
- Frozen: The plants are incased in the ice block. The mutation combines Wet or Drenched with Chilled mutation. Flowers can be applied by Flower Froster Sprinkle.
- Chilled: It mainly generates from Pets, such as Misletoad and Tanuku.
- Peppermint: Peppermint Vine Seed grows and is transformed into Peppermint mutation.
- Glacial: The rarest mutation which applied by Frost Dragon pet. This mutation require Frozen plants. Furthermore, it is able to increase XP.
How Mutations Are Triggered
Players are able to actively yield mutations instead of depending on luck. There are three universal methods as follows to get more mutations with efficiency.
Global Weather Event
This is the easiest method without any tools or pets. According to Ribbon the Elf, snow falls on the entire map for every ten minutes. When it falling, all plants instantly mutate into Snowy plants.

Tool Trigger
The player can use tools to trigger Christmas mutations. For instance, the Flower Froster Sprinkle (New Item) will transforms the flower-type plant into Frozen mutation in range. Besides, you can use the Mutation Spray Chilled to apply Chilled mutation and freeze the Wet or Drenched fruits.
Pet Passive Ability
Pets play an important role in Christmas Mutation, and Grow a Garden also releases time-limited pets that are capable of mutating plants. While Mistletoad directly gives Chilled Mutation, T-Rex spreads mutations to adjacent plants. To figure out more Christmas pets, you can read our Grow a Garden Christmas Pets Tier List.
Best Plants for Christmas Mutations
Once you've understand how mutations are trigger, you need to choose the best plants for Christmas mutations. Not all plants are workable, thus, we provide three kinds of plants.
Coconut - Largest Quantity
A single Coconut tree yields over 20 coconuts. When the pet activate its ability, you immediately obtain 20+ Chilled mutated coconuts, making it extremely efficient.

Sugar Apple - Highest Quality
The rarer mutated fruits you submit, the higher points you gains. Therefore, you can revovle around Sugar Apple. Although its overall output is lower than coconuts, you will gain far more event points for a single submission.

Lilac / Rose - Sprinkler Specialists
Flower Frost Sprinkle only works on flower-type plants. Lilacs and roses have high planting density, perfect for mass-producing Frozen mutations.

Garden Layouts for Maximum Mutations
A good layout can double your efficiency and help you farm Santa's Surprise Presents faster. If you want the best farming strategies, we provide Santa’s Surprise Presents Fast Farming Ultimate Guide for you.
- Flower Density Layout
You require filling the entire map with lilacs or roses. Then, place a Flower Frost Sprinkler at the center of each flower cluster. This layout highlights players without mighty pets. Besides, The high-yield flowers allow players to obtain massive Snowy mutations.
- Coconut Focus Layout
You need to plant rows of Coconut trees. Afterwards, place Pancakes near the tree bases. Mistletoad will lock the Pancakes and wander around the Coconut area, preventing it from mutating low-value grass or flowers.
Pets That Enhance Mutation
The Christmas Harvest Event offers new special pets that extremenly accelerate the mutation rate. As a matter of fact, we will simply list pets bringing an automated farm.
- Mistletoad: A limited mythical pet used to produce Chilled Mutation for Coconut mutation farming. Beware, pancakes are indispensable.
- Frost Dragon: A divine limited pet capable of converting nearby Frozen mutations to Glacial mutations, granting extra XP to other pets.
If you are building a flower farm, you have to get a Frost Dragon to enhance mutation. - T-Rex: An excellent pet that will spread mutations. If one valuable plant mutate, you will yield a wide area of mutations.
- 60kg Nightmare Mimic Octopus: this pet, a natural imitator, can mimic the ability of any of the pets mentioned above, serving as the key engine for high-frequency farming
