Weather events
The documented weather events, their mutations, and how to plan your farming around each.
Last reviewed: Jun 21, 2026
Weather is the single largest swing factor in Grow a Garden 2. The game ships with 7 documented weather events plus 2 community-reported events (plus a day-night cycle). Two event types exist:
- Standard events — Rain, Lightning, Blizzard. These affect every server regularly.
- Special events — Midas, Rainbow Moon, Blood Moon, Starfall. These are rarer and apply the highest-value mutations in the game.
Weather mutations are the only source of the Frozen, Electric, Shocked, Bloodlit, and Starstruck mutations. (Ice Serpent is a niche exception — it applies Frozen to your own plants as a defensive side effect.) If you want a weather mutation, you must have crops in the ground when the event fires.
The 2 community-reported events (Sunny, Rainbow Flight) are tracked here for completeness but their gameplay effects, durations, and trigger conditions are not yet documented in our source sites — treat them as unconfirmed.

Steps
- 1Rain — growth speed boost (no mutation)
Effect: growth speed boost for every crop on the server for the duration (see /weather for the current reported multiplier and duration).
Best response: plant long-grow-time seeds immediately. This is the optimal event for seeding your next high-value crop.
Multiplier math: Rain does not change your per-crop value, but it increases the number of cycles per hour — an effective income multiplier for any crop harvested during the event window. Model the exact effect in the calculator.
- 2Lightning — Shocked or Electric
Mutations applied: Shocked, Electric.
Best response: if Lightning starts and you have plots with growing crops, do not harvest — let the event apply mutations first. Harvest immediately after the event ends so the mutation is locked in.
- 3Blizzard — Frozen
Mutations applied: Frozen.
Best response: same pattern as Lightning — do not harvest during the event; harvest immediately after. Pair with heavy crops (Bamboo, Cactus, Coconut) to maximize weight factor.
- 4Midas — Gold + Golden Seeds spawn
Mutations applied: Gold.
Pet synergy: equip Golden Dragonfly (Mythic) during Midas to boost the Gold chance on every roll.
Best response: collect every Golden Seed that spawns during the event. Then harvest your existing Gold-mutated crops immediately after the event ends.
- 5Rainbow Moon — Rainbow + Rainbow Seeds spawn
Mutations applied: Rainbow.
Pet synergy: equip Unicorn (Mythic) during Rainbow Moon to boost the Rainbow chance on every roll.
Best response: collect every Rainbow Seed that spawns. Harvest Rainbow-mutated crops immediately after the event ends.
- 6Blood Moon — Bloodlit
Mutations applied: Bloodlit.
Visual cue: the world is tinted red. Bring a Lantern if you want to keep moving at full speed during the event.
Best response: ensure fast-growing crops are planted before the event. A Strawberry planted shortly before Blood Moon can mature and get the mutation during the event window. (For the exact Sheckle payout, model it in the calculator with real base values.)
- 7Starfall — Starstruck
Mutations applied: Starstruck.
Best response: keep one plot of fast-growing multi-harvest crops (Strawberry, Blueberry) ready to harvest at all times so you can capture the Starfall chance when it fires.
Tips
Weather → mutation map
Every weather mutation comes from a specific weather event (or Ice Serpent). There is no other source.
- Rain → no mutation
- Lightning → Shocked (×100), Electric (×70)
- Blizzard → Frozen (×40)
- Midas → Gold (×10)
- Rainbow Moon → Rainbow (×25)
- Blood Moon → Bloodlit (×80)
- Starfall → Starstruck (×45)
- Sunny → no mutation
- Rainbow Flight → Rainbow (×25)
- Ice Serpent pet → Frozen (applied to your own plants as a defensive side effect).
Farming calendar strategy
Because weather events are server-wide and unpredictable, plan a weekly rhythm:
- Morning check. Open the game, see the documented weather events that are known to occur. If a Standard event is active or starting, plant long-grow-time seeds in advance.
- Maintain a permanent multi-harvest floor. Always have multi-harvest crops growing across your plots. This guarantees you capture every event that fires while you are offline.
- During Special events. Equip the matching pet (Golden Dragonfly for Midas, Unicorn for Rainbow Moon). Harvest only after the event ends to lock in mutations.
- Stack weather when possible. If Blizzard and Lightning overlap, the additive stacking can produce a large per-crop multiplier. See the mutations guide for the math.
- Track the day-night cycle.Owl pet's night view distance bonus matters for spotting rare spawns.
Confidence notes
Per the source data: Starfall's duration is undocumented (confidence: likely). Shocked's exact trigger beyond "Lightning-related" is unconfirmed (confidence: likely). The Ice Serpent's Frozen application is verified. We do not list specific event probabilities because the source sites do not document them.
