Front 'yard' is a stand of 130--150 ft D Fir.
Last year one small area (about 50 ft square) has had 4 Hemlock die. Ranging in size from 20 in DBH down to 6", guessing the smaller are from seed dropped by the larger - which I dropped today, 92 years old. The hemlockreceived more sun as of 2 years ago when neighbor to the south removed a few 140 ft D Fir on his property line about 25 ft away from the larger hemlock.
Question is if more sunlight on a mature hemlock can cause them to die. Or is there some hemlock blight going around that I should watch for and clear out all hemlock. This is at my house in town., think there are only a few dozen mor Hemlock on y 3 in town acres.
40 years ago had the largest hemlock in the yard die, that one was about 30 in DBH and over 100 YO at the time. A couple other hemlock a few hundred feet farther Norht died about 10 years ago also.
All D. Fir (and bigleaf maple) are healthy.
