Hi,
Just curious as to what’s going on here? The inner branches and foliage are turning yellow, then brown. I also have what I believe to be a Western redcedar exhibiting the same thing. Would this be a seasonal issue? This tree is new to me, but survived the hot summer well I thought.
Most coniferous species drop their oldest foliage during the end of summer or during fall. These needles/pads were shaded out during the growing season and are the least photosyntheticly efficient so the tree discards them in fawor of the new foliage. The time varies from species to species.
If you can’t find any pests diseases and it’s all over the tree not just in a few places I wouldn’t worry about it.
