Disease Spread-Leyland Cypress to Arborvitae?

Q: We just took out my beloved Leyland cypress because they were dying. I want to replace them with American Pillar arborvitae in the same spot. If my cypress were diseased, will that spread to American Pillar?

A: In my experience, arborvitae and Leyland cypress don’t get the same diseases. ‘American Pillar’ seems more drought tolerant as well. I have a big list of good plants for screening at http://www.walterreeves.com/landscaping/plants-for-screening/.
