Browning of larch needles in summer

Question

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!

Answer 1

There can be a few reasons for browning of Larch Tree needles; from pests to a few diseases.
It may take further inspections to determine the issue.
