Hello,
A quick note on harvesting to help some of you out:

Watering: A single watering session throughout the entire growth period is enough to aim for a perfect pumpkin. Remember to also take precipitation into account—rain, snow, and hail may already provide the necessary water.
So, keep an eye on the weather forecast before you water.

Weather & Protection: Any protective measures must be tailored to the expected weather conditions. These protections last for 9 hours, so be sure to monitor when they expire and plan ahead to renew them. A weather radar is available to guide you—don't hesitate to get one! (And don't forget to keep an eye out for crows at night.)
If mold keeps appearing in your harvests, take a moment to review your watering schedule, the weather conditions during the growth period, and the protective measures you used. The tutorial is still available; feel free to take the time to watch it again.
