Answer: Italian cypresses are very adaptable and will grow in clay, sand or loam soils, as long as it drains well. 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 once a day, 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 to help your plants establish a deep root system.
Best wishes with your Leyland Cypresses!
