Q: We have young limes and lemons in half whiskey barrels. We tried to cover them and even provided heat under the covers, but we had a mixed success. Some of the citrus have green leaves and stems, and others don’t have anything green left from the Christmas freeze. When will we know what is going to survive?
A: Be patient; even your plants without any green foliage right now may survive. The key there will be if the surviving plants will be the desirable tops or less-desirable rootstocks. If the new leaves that appear are the same as those that existed before the freeze, your desirable tops are restored.
