We offer a variety of resources, classes, and opportunities for aspiring and experienced gardeners, DIY home lawn care, and commercial horticulture operations. 

Have a gardening or lawn care question?

Garden Hotline - (316) 660-0190
Monday-Friday, 9:00am - 12:00pm and 1:00-4:00pm

If you have an ailing plant, we recommend that you try emailing pictures of your plant to the Garden Hotline email. For best results and fastest response, we would encourage you to send multiple pictures, as listed below.

For pest or disease diagnosis: 

  1. One picture of the entire plant or garden area
  2. One picture of a branch or affected area
  3. One close up, in focus picture of any symptoms of concern (leaf spots, holes, discoloration, etc.) 

For plant identification: 

  1. One picture of the entire plant or garden area
  2. One picture of leaves or branches
  3. One picture of any flowers, flower buds, or seeds visible

Additionally, you can find answers and resources for the most common questions at the Horticulture Resource Center

For a soil fertility test, please view our Soil Testing Procedures page for details on that process. (Please note: Soil testing only provides nutrient information, it does not test for diseases in the soil.)

Want to know more about the Extension Master Gardener Program?

The Extension Master Gardener program is a volunteer program through K-State Research and Extension. The Sedgwick County Extension Master Gardeners operate the Garden Hotline, maintain demonstration gardens, teach youth, and hold events and tours for the public. 

On Our Grounds

Our mission is to ensure that the grounds surrounding our facility serve as a learning environment for the public. We feature a Demonstration Garden that is open year-round and offers educational exhibits with raised growing beds, seasonal vegetable plantings, a compost demonstration, and an outdoor classroom area. The Extension Arboretum was created in 1994 and serves as a resource for Sedgwick County citizens. The Arboretum showcases specific trees, shrubs and other plants that are ideal for growing in our County. For more information on the gardens, visit the Demonstration Gardens page.

Current Gardening Topics
My irrigation system is already turned off for the winter - should I be watering during the winter?  If so, what plants are most important to water?  How much water do they need? 

The weather this winter has been dry, and unseasonably warm, making winter watering an important gardening task to do right now. Trees and shrubs planted within the last year, lawns planted or overseeded this past fall, and evergreen trees are the most important plants to focus on watering. Water anytime the temperature is above freezing and the ground isn’t frozen. Water slowly so that the moisture soaks 6-12 inches deep into the ground. Winter watering once or twice per month is usually sufficient. Don’t forget to disconnect your garden hose when you finish! 

My pin oak tree has the strange growths on the leaves. What is it and what can I do? Is this what causes the Oak Itch Mites? 

There's a good chance that what you are seeing is Oak Vein Pocket Gall. Many local pin oak trees have been severely affected for the last few years. This gall is not associated with the itch mites. That is caused by the Oak Leaf Marginal Gall. The best option is to do nothing, because there are not any effective insecticides. 

What variety of ______ should I plant in my yard?
