Why do the flowers fall my pink dawn chitalpa just weeks after they bloom in the spring-and don’t return untl nxt yr

Question

The planting instructions (I live in Mesquite, Nv) said deep infrequent watering. However, all the chitalpas in my neighborhood are on drip systems. My tree has two drip lines delivering one gallon per line twice weekly. After reading your article, I suspect I am overwatering. Any suggestions

Regards
