Here is another post from Larry Ginger of "American Lawn Care" in Des Moines. Larry has been keeping us updated on late grub damage and fall seeding on lawns that he manages. Below are some pictures from Pleasant Hill, Ia showing active grubs on November 9. I am going to have to change my teaching notes on this. Generally the grubs have burrowed deep underground by this time, but here they are in November.
Larry also reports an 800% increase in his fall seeding business. He is using a three-way blend of Falcon IV, Five Point and Six Point turf-type tall fescues. He will send us some pictures of newly seeded lawns next week.
I have also been seeding areas that had been established to Kentucky bluegrass in the past, but were lost to the drought this summer. I have tried turf-type tall fescues as well in some areas and will report the success with this next season. My main concern is how well they will blend with the Kentucky bluegrass remaining on the area.
