I need help identifying some yellowing/dying in some yews. These are in a cortyard in Northern Virginia. The yews in more shade show no signs of this dieback. The soil moisture is appropriate, i.e. no wet feet, and the PH is 6.3.

Notice that the leaves yellow then a brown spot apears in the middle of the leaf and then spreads to turn the leaf brown. Any ideas?

Thanks,
William
