Smudge Pots

Smudge Pots

Fruit growers will sometimes use smudge pots to try to protect their crops from a possible killing frost, particularly on clear, cold nights. A smudge pot is a portable heater/burner which produces thick heavy smoke. Fruit growers place a number of these around the orchard in the evening to prevent the crop from freezing at night. Do smudge pots actually work? Why?

  • A. Yes. They work simply by heating the air in the orchard to keep it above freezing.
  • B. No. They don't work. They can not supply enough heat to keep the orchard from freezing.
  • C. Yes. They work by producing a heavy smoke layer over the orchard which prevents heat loss by radiation to the night sky
  • D. I think someone should notify the Pollution Control Agency.
