Lawn care

Asked April 25, 2013, 9:50 PM EDT

We built a new home in Parkersburg after recovery from the 2008 tornado. We decided to seed our lawn rather than sod. Last year we had a problem with grubs which has made the grass be in clumps and very rough. We hope there is something that can be done rather than starting over and would very much like to have someone come and discuss our options. Is that possible? Thanks so very much for your attention given this concern.

Thanks for contacting eXtension with this concern. Your action to seed was wise, and the seed you used must have had a mixture of fescue, Kentucky bluegrass, and ryegrass. In addition to your grub problems last season, Iowa experienced a severe drought. The white grubs liked the bluegrass and whatever was left may have been killed by the drought. The result was the 'clumpy' grass, mainly from the fescues, but also may be from the ryegrass.

Because your lawn is still developing, it is suggested that you re-seed again (over the top of what is already there) a couple of times this year. You may opt to leave the Kentucky bluegrass out of the mix and just go with turf type tall fescue and perennial ryegrasses. The turfgrass specialist at Iowa State reseeded his personal lawn with the turf type tall fescues and they survived the drought beautifully, and now that the lawn is established, is no longer distinctly clumpy.

You may also want to get his opinion on this matter: Dave Minner (dminner@iastate.edu).
