Grow a Garden September event guide: every harvest bonus explained

The Harvest Moon event is live until early October and it changes the value of night-time crops dramatically.

Plant moonflowers in every unlocked plot, water once, then log off for two hours. Night crops mature on a real-time timer, so idle time is genuinely more efficient than active play here.

Do not sell moonflower or lunar pumpkin seeds. Both are event-exclusive and historically resell at four to six times their base price once the event ends.

HARVESTMOON grants a rare seed pack and is the only event-limited code so far. It expires when the event ends, so redeem it now even if your plots are full.
