Pro Tips

  • Face the cold frame south to capture maximum winter sun
  • Prop the lid open on days above 40ยฐF to prevent overheating
  • A polycarbonate lid insulates better than glass and won't shatter
  • Lay a layer of straw inside on hard-freeze nights for extra protection
  • Cold frames extend your season by 4โ€“6 weeks in both spring and fall
