I live in San Ramon, CA. , which is 50 miles east of San Francisco. In winter there is frost at night and in the early morning. I planted a kaffir lime tree about 24 inches tall a month ago. The tree has dropped all its leaves. We had several nights with temps below freezing. Is the tree going to survive, and is it normal for kaffir lime to shed its leaves?

It is not normal for the plant to shed its leaves,but that being said, it can recover from this. You will need to make sure it gets exactly what it needs in terms of water and light.If you are fertilizing, stop until the leaves regrow as this can damage the roots since the fertilizer has nowhere to go.
If you expect more frost,make sure that the tree is covered at night (a bedsheet will do) and that that the covering is taken off first thing in the morning.
