It's hard to give good suggestions based on such limited information, i.e., are your plants in pots or outside; how long have you had them; what is the history of the plants; etc, etc. However, I can say that in general, falling leaves is most often a sign of water imbalance. Without knowing anything else about your trees, I would suggest you water more, unless you water a lot and the soil is always wet, in which case you should try watering less.
