I'm not sure what's going on with your cypresses! Italian cypresses are very adaptable and will grow in clay, sand or loam soils, as long as it drains well. I'ts possible your clay soil is remaining too wet for good root establishment. If so, dig a generouse hole and amend the soil with compost or rice hulls. Mix it in well, and over a large, deep area to make a good environment for the roots. Once established they get along with about one-inch of water per week during the growing season. Italian cypress needs exposure to full sunshine for healthiest growth. If you're watering more often than once or twice a week, you're keeping the soil too wet, which is eliminating oxygen. Without oxygen, the roots will die. Water deeply once each week during the growing season (twice if the weather is hot) to help your plants establish a deep root system. Best wishes with your Leyland Cypresses!
