Water And Frost
From how many acres could I keep off a freeze of oranges with 1000
gallons per minute? The water is at 65 degrees.
The amount of water will prevent frost over as large an area as you can
cover with the water, so as to thoroughly wet the surface, but the
presence of water will only be effective through about four degrees of
temperature and only for a short time. If, then, the temperature should
fall below 27 degrees and should remain at that point for an hour or
two, it is doubtful if the water would save your fruit. Water is only of
limited value in the prevention of frost, and of no value at all when
the temperature falls too low.
