Leyland Cypress removal

Leyland Cypress were planted by the Developer in common areas or by residents in their yards adjacent to common areas. These fast-growing trees were expected to make excellent privacy screens, but they proven to be short-lived and prone to disease. Many now have evidence of Seiridium Canker, a fungus that destroys the food- and water-conducting tissues beneath the bark of the tree. Reddish brown needles and dead or dying limbs are characteristic of Seiridium Canker. Once the fungus gets into the trunk, a tree will usually die. 

The fungus is contagious; it spreads through roots by physical damage, by insect pests such as bark beetles, or by birds and other contacts that travel from tree to tree carrying spores. There is very little to prevent its spread once it has established itself in an area.
