It's your chance to peek behind the scenes, talk with the experts and learn about the latest varieties and methods for achieving growing success.

K-State Research and Extension horticulture research develops its list of recommended grasses, flowers or vegetable varieties through university research conducted in Olathe to determine what grows best in our Kansas City landscapes.

  • bottled water,
  • seminars,
  • air conditioned classes, and
  • demonstrations.
Free soil tests

Johnson County residents can bring their soil and get one free soil test, complements of Johnson County Stormwater Management. A soil test determines the nutrients in the soil. It is important to know the nutrient levels to grow healthy plants. Go to www.johnson.ksu.edu/soiltest to learn how to take a soil sample.  At least 2 cups of dry soil are needed for a proper test.


The Research Center is located at 35230 West 135th Street, Olathe. The entrance is approximately nine miles west of Highway 7 on 135th Street. Admission is $5 at the gate.
