ISU Extension Welcomes New Horticulture Program Coordinator

Rock Rapids, Iowa — Iowa State University Extension and Outreach has a new plant person in northwest Iowa.

Dawn Henderson is their new horticulture program coordinator for Lyon, Osceola, Sioux and O’Brien Counties. Her first official day on the job was June 10. She takes over for Margaret Murphy who moved to Wisconsin to be closer to family.

Henderson’s responsibilities include: answering horticulture-related questions, providing consumer horticulture programming throughout the four-county area, maintaining a strong local Master Gardener volunteer organization and working with the local community and donation gardens.

Henderson is a 2019 graduate of Iowa State University with a Bachelor of Science in Agronomy. Previously, she served as a water resources intern with Iowa Learning Farms and Water Rocks!; an agronomy intern with local ISU Extension and Outreach Field Agronomist Joel DeJong; and a summer naturalist intern at the Dorothy Pecaut Nature Center.

Henderson looks forward to the position and working with local communities.

She says, “Community education has always been a passion of mine and I have been interested in working with Extension since the beginning of college.” She says she is excited to combine her passion for agriculture with the opportunity to work directly with the public on conservation education.

Henderson will be based out of the ISU Extension and Outreach Lyon County office in Rock Rapids with frequent travel around all four counties (Lyon, Osceola, O’Brien, and Sioux).

To welcome Henderson, you can stop by the ISU Extension and Outreach Lyon County office located at 710 North 2nd Avenue East in Rock Rapids, call 712-472-2576 or email
