Johnson County Extension Master Gardener Public Garden Tour 2024


Rosche Garden The Garden Tour returns May 17 and 18, 2024. Hosted by the Johnson County K-State Research and Extension Master Gardeners (EMGs), this beloved biennial event is your chance to peek inside and tour six of the most beautiful private gardens in Kansas City.

You may begin your tour at any garden. We request you visit each garden only once. You are able to attend both Friday and Saturday from 9AM-5PM  if you prefer to split the gardens up.

This year, in addition to the six wonderful gardens,  we have expanded the tour and will be offering an Extension Expo with educational stations. Garden themed hand crafted boutique shopping will be available as well at our Garden Thyme Marketplace.

Proceeds from ticket sales support Extension Master Gardener projects and programs here in Johnson County. 

There are a few changes to this year’s tour. 



 Tickets are SOLD OUT! Garden Tour will return in 2026. The Extension Expo and Garden Thyme Marketplace are an option and require no ticketing to attend at 11811 S. Sunset Drive in Olathe.


  • The Tour will be primarily paperless. When you purchased your ticket, you received addresses and a map of the gardens locations in your confirmation email. An additional courtesy reminder email was sent 9:45AM on May 15th.   Also available digitally on our website below are educational fact sheets on topics such as irrigation, peonies, trellising plants, tomatoes, sedums, and small spaces in the garden.
  • We encourage carpooling to the gardens.

The tour takes place rain or shine. No pets or strollers. No refunds on unused tickets. We hope you enjoy these gardens as much as we do and hope to see you on the tour!

Why We're Different

Our garden tour is unique! Each garden is owned and maintained by one of our EMGs. By opening up these private gardens to the public you get a rare chance to wander through your neighbor's backyard and see and learn from local experts.

Information about each garden and educational fact sheets full of practical tips and ideas are accessible digitally.

As a tribute to Dennis Patton, K-State Research and Extension Horticulture Agent and head of the Johnson County Master Gardener program who passed away on March 16, 2024, our Public Garden Tour educational materials are drawn from the wide array of educational materials that Dennis wrote or contributed to during his 35 years with our program. We honor his legacy of horticulture education by sharing his knowledge with you.
