Frost Protection Ideas Needed

[RollTideChicken]

So we have a frost warning for tonight and I have three fruit trees in full bloom: Santa Rosa plum, Methley plum, and a peach.
The SR plum and peach are smallish and I think I can rig some bags together to help them, but the Methley is about 13ft tall and wider than that.
Plastic sheets from hardware stores around here are pricey, and honsetly I could just buy alot of plums for that money.
We might have some old bed sheets but, would they do the trick? Any other thought or ideas?
Thanks!

Usually, when there is a frost, the air is calm, so you may just be able to take an arm load of sheets out and drape over each of the trees, if the trees are not too big.

Don't orchards run sprinklers to protect the trees with ice during freezing events?

I just got in from spraying my peaches with the water hose. The water freezes, instead of the blossoms. It acts as an insulator. Good luck!
