Alien Invasion Event

The Alien Invasion Event premiered on February 28, 2026, and it is one of the more mechanically interesting late-cycle drops because it didn't just hand out a cosmetic — it shipped a new seed plus brand-new weather types that change how the garden plays during the event window.

The standout here is the weather layer. New event weathers in Grow a Garden typically apply their own mutations to fruit, so the highest-value move is to have a wide spread of mature, harvestable crops waiting when an alien weather rolls in, then mass-harvest while the buff is live. Don't sell early — let plants sit so the weather can stack its mutation onto the largest possible batch.

The new seed is the collectible to lock down first, since event-exclusive seeds are the items most likely to gain trade value after the theme rotates out. Because the row doesn't list fixed rewards or a hard end date, treat this as an active, weather-driven event rather than a one-time merchant: log in across multiple sessions to catch the alien weather cycling, keep empty plots ready, and bank seeds for replanting between waves.
