Herbal Distancing: Keeping Boxwood in Your Nursery Free from Blight

By Dr. Jerry Weiland • January 30, 2026

Learn how your nursery production practices can impact boxwood blight risk and your potential for outbreaks. Whether you’re currently dealing with this disease or working to prevent it, understanding key risk factors is essential for protecting your entire boxwood inventory. Join plant disease expert Jerry Weiland as he examines real-world case studies demonstrating how boxwood blight enters nurseries and spreads via common production activities. This webinar will cover critical factors that influence disease development and spread, including plant size and spacing, cultivar selection, environmental conditions (temperature and moisture), and fungicides. You’ll leave with practical management recommendations and actionable strategies for preventing and controlling boxwood blight in your operation.
