Too much water prevents roots from getting oxygen and they die. Yellowing of the foliage can follow such stressful conditions. You'll have to dig down a few inches to feel the soil to determine if it is soggy or just moist. Yellow leaves may also be due to a lack of nitrogen fertilizer. It is also rather normal for some evergreens to turn their older leaves yellow before the drop in the spring. Usually this us a little earlier and somewhat coincides with the onset of new growth.
Thanks for the question. Please stop in again soon!
