How can I protect lemon trees from frost?

Lemon   

I recently move to a new place which has several lemon trees in the yard. I do not know what kind they are but there are currently fruits on them which are not yet ripe. I live close to San Jose and temperatures here are meant to go below freezing briefly and I don't know if I should protect the trees somehow. Is there an easy way to do this? Many thanks

Karen Cassidy commented,
It sounds like your trees are reasonably well-established, so it might be more a matter of protecting the fruit and then dealing with any minor damage to the tree itself after frost, This site has great advice on both subjects :) http://homeorchard.ucdavis.edu/8100.pdf

Use Burlap bags, blankets or cardboard wrapped around the tree, trunk. In wet weather use plastic on top of the burlap/blankets. Keep the soil moist as moist soil radiates more heat (so no mulch). Consider using christmas lights which provide a little bit of heat. If very cold put a high watt spot light at the base shining up, under the blankets

I grow key limes in my area via espalier on a south wall:

It's too late to do that with your particular tree, but if you ever plant another one - it works.

In addition to David's excellent advice, you can also fill a 55 gallon drum with water and place it beneath the tree next to the trunk.

We hit the local thrift stores for cheap blankets and sheets. They only cost a couple bucks there.
