What's the best way to protect 3 to 5 year old citrus trees? Satsumas, Meyer's lemons, and navel oranges.

Water them extremely thoroughly, like to the point of soggyness, cover the ground out to the drip line with straw/pine needles/leaf litter and mound it up as high as you can, string as many incandescent lights as you can, preferably c9s, in the foliage, cover it with burlap or a plant wrap, and tie it down tight around the base of the trunk to keep cold air from leaking in. This kept my Persian lime trees from dying in "The Freeze" in SE Houston almost two years ago so I figure it bought me about 15 degrees. All three of those you listed are more cold tolerant than limes, which are the wimpiest of citruses, so it'll probably do the job.
