The most common citrus leaf problems for lemon, lime and orange tree leaves is leaf drop. This can be caused by any number of reasons, but the most common is a great fluctuation in temperature, causing the leaves falling off a citrus tree to continue to drop until the tree can handle the temperature once more.

Citrus trees like warm weather but do best in temperatures that don’t go much above 60 to 65 degrees F. Further, whether you have your citrus trees indoors or out, you should make sure the temperature doesn’t fluctuate and is more of a constant temperature. This will definitely help stop leaves falling off a citrus tree.
