What would it mean if my three plants are now have leaves turning yellow? I planted them in February and until now they were growing and looked healthier. Too much water?? I have a sprinkler system and it is on 15 minutes on even days. they actually looked better before my new system.

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!
