The June 15 Grow a Garden 2 weather and mutation update gives players a clearer reason to watch the sky before planting, harvesting, or stealing. Community update tracking names the update as New Weather Events and Mutations Discovered, and several guide sources now list Starfall, Rainbow Moon, Blood Moon, Starstruck, and Bloodlit as part of the live weather and mutation pool. Roblox confirms that the game itself was updated again on June 16 UTC, but the official Roblox description still only names the launch systems. For the public page, write the weather and mutation changes as player-documented update coverage rather than developer patch-note wording.
The biggest gameplay change is the Starfall to Starstruck link. Beebom, TechWiser, TheGamer, Game8 search results, and Fandom all connect Starfall with the Starstruck mutation. Players should treat Starfall as a farm-prep window: plant or leave valuable crops growing before the event starts, then check which crops receive the mutation after the sky event ends. The exact multiplier is not stable across sources, so this update page should not lock one number into the main version summary. Put the current multiplier on the mutation or calculator page only after a live test resolves the conflict.
Blood Moon and Bloodlit are the second major addition. TechWiser, TheGamer, and Fandom connect Blood Moon or Bloodmoon with Bloodlit crops. That matters because night is already tied to stealing in the launch description. Weather coverage now needs to separate ordinary night stealing from Blood Moon behavior: normal night enables stealing, while Blood Moon is a special weather state that can apply Bloodlit. Players checking defense pages should know that night guides, mutation pages, and crop value estimates all need a Blood Moon note.
Rainbow Moon also changes the night-event coverage. Beebom and TechWiser list Rainbow Moon as a two-minute event, while TheGamer also names Rainbow Moon in the weather list. Sources do not use one identical description for its reward behavior: some describe rainbow seed spawns, while others describe rainbow results from stealing. The safe published wording is that Rainbow Moon is documented as a special night weather event tied to rainbow crop or seed outcomes. Do not turn it into a fixed farming route until live testing confirms whether the main reward is seed spawning, rainbow stealing, or both.
This update affects more than the update index. Weather pages need Starfall, Blood Moon, Rainbow Moon, and timing notes. Mutation pages need Starstruck and Bloodlit entries with source-linked triggers. The calculator needs those mutations hidden behind a checked multiplier value, because sources disagree on exact numbers. Beginner and night-stealing guides need a short warning that weather can change the value of crops during the same day-night loop. The best player action after this update is simple: watch the in-game weather, note the event name, record which crop changed, and update the mutation value only after repeatable checks.
