Its going to get down to 25-28 degrees and I have too amy trees to run them all in the green house plus I have a sciatica attack going on. If I went out during the hours of freezing and misted or sprayed would this thwart injury?
This...though how about using a sprinkler if the trees can't be moved? If it's only going to be below freezing for a few hours, that might work, though 25F is pretty cold.
We use oil lamps, those breaky-thingies you put in your winter gloves that produce chemical heat, encased candles, and for everything lower than -2°C we spray water.
A barbecue would last through the night as well, toss some unannealed wire on it and you'll hit two rocks with one bird.

I wonder if sprinkling with a warm water source on a timer 15 minutes in every half hour would work. Sorry to hear David, I know your adversary sciatica, it's almost impossible to do what you are needing to do.
