Frost damage in lime tree

Of the citrus, limes are the least tolerant of cold weather. They are notorious for defoliating. After our cold snap, I imagine that your tree looks forlorn but do not lose hope for its recovery. You will not know the extent of cold damage until March. It may be that some of the branch tips and twigs have been killed but the rest of the tree should still be quite alive. If you scrape off the bark and see green beneath, it is alive. Wait to prune or feed until late March. New leaves should resprout in April. If the tree is in a container or planted where it will not receive rain, water periodically through the winter to keep the soil from completely drying out. If there is a chance we will have another freeze, cover the tree with burlap, a sheet or frost blanket to prevent further injury.
