The tree is stressed from a watering or nutrient issue or pest of some kind. Check the soil for excessive moisture. You may need to improve drainage to the area. Also, get a soil test to see what, if anything, is lacking and fix as necessary. Finally, check the tree carefully for signs of pests. Neem oil is an effective treatment for most insect pests.
