When to plant popcorn
Popcorn is a warm-season crop that must be direct seeded. Plant after the soil has warmed; seeds germinate best when soil temperatures are close to 60 degrees F (University of Minnesota).
Popcorn is timed by season rather than your frost dates, so the planting calendar does not generate ZIP-specific dates for it. Check the cited sources below to fine-tune for your area.
