Johnson County K-State Extension
We are dedicated to a safe, sustainable, competitive food and fiber system and to strong healthy communities, families, and youth through integrated research, analysis, and education.
Bringing K-State to Johnson County
Here at the K-State Johnson County Extension Office, we pledge to serve our community in a variety of ways, from health and nutrition, to agricultural and horticultural needs, money management, and much more. We exist to help others through Kansas State University knowledge and information in order to better serve our communities, specializing in problem-solving, education, and community service.
Since 1917, the Johnson County Extension Office has dedicated our time and resources to ensure that the community of Johnson County continues to grow and thrive.
What's Happening
Fall is the best time to fertilize cool-season lawns, but applying nutrients your lawn doesn't need can waste money and harm water quality. Start with a soil test to learn exactly what your lawn needs before you fertilize. Johnson County residents receive one free basic soil test each year.
Bugs chewing holes in your leaves? Strange spots on your tomatoes? Wondering when or how to prune a tree or shrub? The Garden Hotline connects you with local Extension horticulture experts who can help identify problems, answer your questions, and provide research-based solutions for lawns, landscapes, flowers, trees, and vegetable gardens.
Newsletters
Our newsletters are created by our agents and staff here in the Johnson County office. These newsletters are written on timely topics that impact our county residents and the Kansas City area.
