Extension programing is the major driver behind many of my research projects. My position provides opportunities to work closely with growers and Extension agents across the state. While my primary responsibilities revolve around ornamental production, I also work variety of specialty crops including Christmas trees and greenhouse vegetables.

Some of my current Extension projects include:

  • Developing an E-book curriculum for small to medium scale greenhouse vegetable production
  • Improving herbicide application effeciency for container nursery production
  • Updating Christmas tree fertilization and lime recommendations for Alabama
  • Building a case for improving irrigation effeciency in container nurseries
