We will probably get out 1st freeze tomorrow night . It is particularly upsetting as I have a large crop of tomatoes (green), peppers (also green) and eggplant. Here is the situation.....From my prior experience with the weather here I see it only going to 32 degrees for about 2 to 3 hours at most. If I put spray water on the garden for those hours could I get past this light but killing frost? Any other suggestions will be very welcome. Thanks!
