Do you have a specific problem?

Our office is ready to help.  Due to Covid 19 we are encouraging the use of pictures to begin the diagnosis process.  Pictures are very helpful in diagnosing most common plant problems. 

Email pictures to jlgraves@ksu.edu 

Multiple pictures are needed:  close ups of the specific problem, a picture of the entire plant and if possible a picture of the environment around the plant itself.  Please do not zoom in with the camera, rather take a very clear and focused close up shot and several other shots of the full plant and site.

You may also bring in soil (for soil testing), turf, tree, weed, and insect samples to our offices for evaluation.  Samples may be dropped off and you will be then be contacted regarding the diagnosis.  Suggested treatments or solutions will be provided by Central Kansas District horticulture agent Jason Graves.

If you bring a plant sample, please bring a representative sample of the plant, preferably with several leaves on a branch or stem, including flowers, fruit, or other distinguishing characteristics. For lawn samples, bring in a 3" diameter core, including roots.
