Browning of larch needles in summer

Zone zone 3 Canada | Pamela Chalmers added on June 29, 2017 | Answered

I have two coniferous larch trees that the needles are turning brown and falling off, even though they have healthy new growth on each branch. I cannot figure out why as I have two very close neighbors whose larch trees look great. I planted these trees about four yrs ago. Sorry no photos!
