Italian cypress can thrive in the Mediterranean climate of Los Angeles, California. Tall and elegant, often soaring to heights of 40 to 100 feet with a width of 5 to 10 feet, Italian cypress trees can be seen accenting driveways and walks or as a screen between properties. After your Italian cypress has established its root system, one to two years after planting, it is tolerant of the drought-like summer conditions of Los Angeles. This, of course, does not mean you do not need to occasionally water it properly.
Place mulch in a thickness of 3 to 5 inches around your Italian cypress tree, spreading it about 3 to 5 feet wide. Thickly mulching around the base of your Italian cypress will retain the moisture in the soil longer and keep weeds and grass from growing close to the roots, which can result in competition for water.
Water your Italian cypress tree with a hose or drip irrigation system so that it receives a deep soil penetration of water. Allowing the water to seep well into the soil will promote deeper root development, which requires less frequent watering.
Maintain your deep watering every one to two weeks during dry periods.
