Answer: The symptoms sound suspiciously like root rot, especially considering the cypresses are planted near a grassy area that is frequently watered. If you're using a sprinkler system, try to redirect the water so it doesn't include the soil where your cypress trees are planted. If you hand-water, don't apply water to the soil around the trees more often than once each week during the growing season. Other than drying out the soil, there's not much else to offer. If the cypress are otherwise healthy, they should recover once the soil dries out a bit. Good luck with your trees!
