The Italian cypress (Cupressus sempervirens) is a columnar-shaped tree that can reach 70 feet in height, but usually reaches about 30 to 40 feet tall and no more than 10 feet wide. Native to southern Europe and western Asia, the Italian cypress is an evergreen conifer with fragrant, dark-green, needle-like foliage and horizontal branches. The Italian cypress grows best in USDA hardiness zones 7 through 9, where winter temperatures don’t drop below 5 degrees Fahrenheit. You should plant your Italian cypress in full sunlight where it has some shelter from cold winter winds.
Water your Italian cypress once or twice per week throughout the growing season in the absence of rainfall to moisten the soil down to and around the roots. Reduce watering frequency in the winter, watering only during prolonged dry spells so that the root ball doesn’t dry out.
Feed your Italian cypress once each year in early spring with a slow-release, all-purpose tree fertilizer, such as a 10-10-10 NPK formula. Follow the dosage instructions on the label.
Prune your Italian cypress once per year in late winter to remove any dead, diseased, tangled or crossing branches. Regular pruning to shape the tree isn’t necessary.
Spread a fresh 2- to 3-inch layer of organic mulch around the base of your Italian cypress tree once every year in early spring. Keep the mulch about 1 to 2 inches away from the root collar.
Treat your Italian cypress for spider mites year-round by applying an appropriate miticide whenever you detect the insects. Apply an appropriate insecticide to your Italian cypress in late spring through midsummer to get rid of bagworms. Always follow the directions on the pesticide label exactly.

- Apply an appropriate fungicide as a soil drench in early spring to treat phytophthora root rot and reapply the drench in midsummer and again in fall. Spray the Italian cypress tree with a fungicide to control twig blight disease in early summer and again in late summer. Prune away all diseased twigs and branches in midsummer if fungal diseases are present.
- Don't allow the soil to dry out around your Italian cypress, especially during the spring and summer growing season. Also, don't over-water your Italian cypress. Ensure that the water drains freely and the soil doesn't become waterlogged.
