Lawn Care

Asked May 19, 2013, 5:34 PM EDT

We have a Kentucky Bluegrass lawn. Last year it started to exhibit brown/dying patches. We have tried reseeding a couple of times but nothing seems to want to grow in these area's. We have routinely fertilized 4 times per year and did have an excellent stand at one time. We also plugged the lawn several times thinking maybe the mulch had become too thick. Nothing seems to help. It is now very patchy uneven. Is this a disease and if so is there a cure short of starting over? Thanks Lon Tisue

If additional lawn areas begin to turn yellow or brown this summer, dig up and submit a turf specimen to the ISU Plant and Insect Diagnostic Clinic. The clinic staff can examine the grass specimen for diseases. Sample submission instructions can be found at the following website.

If the lawn is thin or patchy in mid-summer, overseed the lawn in late summer. An article on overseeding can be found at the website below.
