Suitable for U.S. Department of Agriculture plant hardiness zones 6 through 9, Leyland cypress is a naturally fast grower, growing 20 to 30 feet tall in the first 10 years, and eventually reaching over 50 feet tall and 20 feet wide.
Keep Leyland cypress trees healthy to minimize the damage from these insects. Knock the insects off the tree with a hard spray from the garden hose, if practical. Some commercially available predatory insects such as lady beetles and parasitic wasps may help reduce infestation.eep Leyland cypress trees healthy to minimize the damage from these insects.
