Landscape Professional Sessions

1:00 pm–3:00 pm – Afternoon Indoor Sessions (Ruby C. McSwain Education Center)

"Ailing Arborvitae and Languishing Leylands: Diagnosing Problems with Cupressaceae in North Carolina Landscapes"
Mike Munster, Plant Disease Diagnostician, NC State Insect and Disease Clinic

Members of the family Cupressaceae – especially arborvitae, Leyland cypress, and junipers – are among the most widely planted trees and shrubs in North Carolina landscapes. Unfortunately, they also suffer from a number of diseases, pests, and abiotic disorders. We’ll explore how to identify many of those problems and when to call for help in making the diagnosis.

"When, Why and How of Plant Growth Regulators"
Andrew Allen, Carolinas Territory Manager, Rainbow EcoScience

Plant growth regulators (PGRs) are changing the tree care and landscaping industry. They streamline maintenance, keeping landscapes beautiful with less work. PGHRS promote plant health, cut costs, and reduce environmental impact, making them essential for modern landscapers aiming for efficiency and sustainability.
